Flip-flops, on the other hand, have their content change only either at the rising or falling edge of the enable signal. This enable signal is usually the controlling clock signal. After the rising or falling edge of the clock, the flip-flop content remains constant even if the input changes.

The input-to-output propagation is not constant — some outputs take two gate delays while others take three.

Latches and Flip Flops. Both Latches and flip flops are circuit elements wherein the output not only depends on the current inputs, but also depends on the previous input and outputs. The main difference between the latch and flip flop is that a flip flop has a clock signal, whereas a latch does not.

Latches and Flip Flops

Latches and Flip Flops. Both Latches and flip flops are circuit elements wherein the output not only depends on the current inputs, but also depends on the previous input and outputs. The main difference between the latch and flip flop is that a flip flop has a clock signal, whereas a latch does not.

The flip flop binary state is taken to be the value of the normal output. When 1 is applied to the inputs of the flip flop, both the outputs go to 0, so both the outputs are complements of each other. When the clock pulse is removed, the state of the flip-flop is unstated. The D flip-flop is the modification of the SR flip flop which is shown in the figure. The D input is sampled during the existence of a clock pulse. If it is 1, then the flip-flop is switched to the set state. If it is 0, then the flip-flop switches to the clear state.

A JK flip flop is a modification of the SR flip flop. The JK flip flop figure is shown below. The output of the flip flop Q is ANDed with inputs k and clock pulse. The flip flop would be cleared during a clock pulse only if the output Q was previously 1. The T flip flop is a single input version of the JK flip flop. The operation of this T flip flop is as follows: Latches are asynchronous — which means, the output of the latch depends on its input; on the other hand, today, most computers are synchronous — which means, the outputs of all the sequential circuits change simultaneously to the rhythm of a global clock signal.

There are four types of latches: This latch can be made from NOR gates. The latch has memory and the output depends on the state of the latch. Therefore, the output at nth instant denoted by Qn is dependent on the output at n-1 th instant, denoted by Qn The D latch is the simple extension of the gated SR latch which removes the possibility of invalid input states. When the enable line of the D latch is high, the output will always reflect the logic level which is present at the D input.

When the input of the D latch falls, the last state of the D latch input is trapped and held in the latch. That is why it is also called as a transparent latch. When enable is asserted, the latch is said to be transparent. JK latch is similar to RS latch. This latch consists of 2 inputs J and K as shown in the below figure. The ambiguous state has been eliminated here: The output feedback to inputs is the only difference we see here, which is not there in the RS latch.

T latch is formed when the inputs of the JK latch are shorted. These are all different types of latches and flip flops.

Hi Aishwarya As per your query please follow the below link https: Hi Renu As per your query Synchronous and asynchronous transmissions are two different methods of transmission synchronization.

Synchronous transmissions are synchronized by an external clock, while asynchronous transmissions are synchronized by special signals along the transmission medium. Please visit our website once http: Sometimes she doesn't say anything and her friends laugh in the background. Other times she will say, 'I love you. Why do you hate me? Can't we be together? She tells people awful things about me that aren't true that threaten my reputation as a real estate agent. I think she needs help from a counselor to get over her anger and issues.

I want her to stay percent away from me. A source told In Touch Weekly that Tarek thought something was up between Christina and Anderson before the El Moussas went public about their split—which may explain why Anderson was present when Tarek and Christina had their massive fight. Tension was high with cheating charges flying. There was no saving the marriage by then. A source says Tarek and Christina hadn't been getting along for a while leading up to their explosive fight and subsequent separation.

The source told I n Touch Weekly that their marriage a "facade," adding, "There were secrets, lies, allegations of cheating, spying on each other, and screaming matches. It was the ultimate house of horrors. They were living a double life.

They weren't only working on a reality show—they were putting on a show. Behind closed doors, they really were a mess. No one ever got to see the real Tarek and Christina until now. It turns out that the El Moussas debates over home renovations allegedly extended off-screen. A network source claims that HGTV is furious with the estranged couple for wrecking their cash cow.

If they can't do that, the network wants to make it seem like they're getting along, at least until their contract is over. They were given an ultimatum: Either finish out your contracts or we'll take you to court [for breach of contract]. The network basically said, 'You guys need to work together, be seen together as a family, walk down the street together.

In the January 16, print issue of In Touch Weekly , a source notes, "They were both riding high. They knew the success of Flip Or Flop is what put them on the map and afforded all their good fortune and their lavish lifestyle. Speaking to People magazine, Christina admitted the couple's relationship fell apart in part because they "went through a lot in a short amount of time. Tarek's battle with cancer; intense in-vitro fertilization treatments; and a miscarriage.

Christina also said she struggled with going back to work four weeks after giving birth to son Brayden. The tension between me and Tarek was high. It got to the point where we weren't even driving to set together. Tarek yells at her in front of production and he is constantly putting her down," the source said. Some of his bad behavior was even caught on camera [in footage that never aired].

Tarek didn't exactly deny or confirm the claims, but wrote on Instagram , "No matter the lies, innuendo, salacious gossip and 'fake news' that is thrown at me from irresponsible media outlets via anonymous sources, I will keep my focus on what matters most, which is co-parenting our children and working hard on our business.

TMZ reported that Tarek and Christina want to keep Flip or Flop going as long as they can, but that's reportedly in the network's hands. However, the odds may be in the estranged couple's favor, because they're crushing the competition in ratings. The pair will fllfill the remainder of its contract with the upcoming season, but a renewal is possible—though it may not necessarily be easy. According to the source, Tarek often "jokes" that he'll rape his estranged wife.

Another HGTV insider admitted that Tarek's behavior was "a huge factor in their marriage falling apart. Christina hit a breaking point and couldn't stand to be around him anymore. She fell out of love…Tarek treated Christina like garbage. People will want to see Christina succeed. She truly wants to have her own career and wants to be separated from Tarek in every way.

People reported that the estranged couple spoke at the Investor Summit in Las Vegas. Both Tarek and Christina posted Instagram photos from the event, where they seemed happy and normal together. Christina wrote on her own photo, "Fun event at successpath investor summit…great meeting our students" via Entertainment Tonight.

Christina and Tarek have stayed pretty far away from each other, physically, during filming, but Christina continues to act like their friendship is hunky dory and uncomplicated. In this Instagram snap from Feb. I [love] each and every one of you.

Tarek and Christina are still working together, but only on HGTV, and it's not going as smoothly as Christina wants the world to believe. An insider told Hollywood Life , "Tarek and Christina are still filming and flipping homes together despite their divorce, however they are simply not comfortable together. The tension on set is high and the entire crew is walking on eggshells every time Tarek and Christina are on location together. They did not look happy to be together, at all.

It's clear they're just going through the motions in an attempt to save their show. Now we're going through a very public divorce but, despite everything, our primary focus is and always will be our kids. We continue to work together, and there's a lot of false stories and a lot of hype, but in the end we're just normal, nice people who just want to be the best parents and coworkers that we can be.

The tension between me and Tarek was high…We weren't able to properly communicate anymore. So by the time we officially did, I felt like a weight was lifted off me…Tarek and I don't discuss each other's personal lives.

It is what it is and we are going through a divorce and eventually we will be dating other people. I'm happy for him and whatever steps he takes in his life and I just hope he's happy. It's invigorating to know I am starting over. It's fun to be able to create my own destiny right now.

There's a lot going on in our lives. We tried the counseling and it just really wasn't working. Tarek revealed for the first time via Today on Feb.

One month later they found out I had testicular cancer. It was very difficult on me. My hormones were way off," he said. It's been three years of hell. I was devastated when I found out. Given that they're going through a very public divorce that bleeds into their personal and professional lives, it shouldn't be all that surprising to find out that Christina and Tarek's decision to remain committed to Flip or Flop hasn't been an easy transition.

Just trying to fight through it and do the best we can. When Entertainment Tonight asked Tarek about Christina's split from Anderson, he admitted, "I found out from the internet, you know?

I do not ask personal question. I do not want to get involved. The best thing for me is to focus on myself, and not worry what she is doing.

I don't know where the future is going to take me, but you never know. We were arm in arm and for many, many years, we were the couple that other couples would be jealous of. All the married friends would say, 'Man, you guys are the best, you get along so well,' and over time, it just started to fade. TMZ reports that both Tarek and Christina El Moussa are over one another enough to nix any talk of ever getting back together, but that they're getting along better thanks to a famous life coach.

Tarek reportedly had been working with life coach Tim Storey, who's also worked with Robert Downey, Jr. Storey had a sit-down dinner with the couple to discuss the split and how to go about co-parenting and working together in a healthy and productive way. Unfortunately for us, the meeting was not recorded for the show.

A source told E! News that Tarek's temper took a toll on the marriage. He can go crazy. He treated her poorly… She put up with a lot. I think she really lost herself in that relationship. A source told I n Touch Weekly that Tarek actually checked into rehab after his blowout fight with Christina in May , but before the couple filed for divorce.

The estranged couple's drama has been ratings gold for HGTV, netting up to 17 million viewers an episode — and the network has apparently given in to their demands, because the show will return for a episode season 7, Variety reported April 24, , making it the longest season ever of the series. While the couple has separated, each one has turned the page to a new life that includes a continued commitment to running their house flipping business together and delivering fresh episodes of Flip Or Flop ," HGTV's website announced.

Christina said in a statement, "Tarek and I have been working together for a long time and we look forward to continuing to work together on Flip Or Flop. Considering Spedding isn't famous, it's pretty clear she's enjoying her newfound infamy post-split, while Tarek continues to fly under the paparazzi radar. In Touch reported that Spedding has a checkered past. In June , a woman named Tracy Diaz claimed to have been in a relationship with Spedding while he was allegedly hooking up with Christina.

She told the magazine, "I've been seeing Doug for almost four years. He hasn't officially ended our relationship.

Flip-flops and latches are used as data storage elements. A flip-flop is a device which stores a single bit (binary digit) of data; one of its two states represents a "one" and the other represents a "zero". Flip-flop circuits are interconnected to form the logic gates for the digital integrated circuits (IC s) used in memory chips and microprocessors. Flip-flops can be used to store one bit, or binary digit, of data. The premise of Flip or Flop is simple: Tarek and Christina buy houses and flip them to sell. But something almost always goes wrong. Beyond the on-screen drama, there's plenty that happens behind the scenes.
