Behaviourally, a flip-flop (by your definition) is a single-bit memory that happens to be edge-triggered. In practice, the implementation magic required to approximate edge-triggering requires a second storage element! @OliverCharlesworth: Well, it is an implementation detail. As well as a physical, behavioural, structural, and topological detail.
Daha fazla öğreninD flip-flop operates with only positive clock transitions or negative clock transitions. Whereas, D latch operates with enable signal. That means, the output of D flip-flop is insensitive to the changes in the input, D except for active transition of the clock signal. The circuit diagram of D flip-flop is shown in the following figure.
Daha fazla öğreninThe flip flop contains a clock pin instead, which reacts only at changing pulses (level shifts). Think of a square wave. The transient time between off and on;off and on is the time in which the circuit reacts to input signals. Only then is it available to change, not when the pin is stable and fully on.

Daha fazla öğreninFlip-flop is a circuit that maintains a state until directed by input to change the state. A basic flip-flop can be constructed using four-NAND or four-NOR gates. Types of flip-flops: SR Flip Flop; JK Flip Flop; D Flip Flop; T Flip Flop; Logic diagrams and truth tables of the different types of flip-flops are as follows:

Daha fazla öğreninFlip-flops are subject to a problem called metastability, which can happen when two inputs, such as data and clock or clock and reset, are changing at about the same time. When the order is not clear, within appropriate timing constraints, the result is that the output may behave unpredictably, taking many times longer than normal to settle to one state or the …

It has the input- following character of the clocked D flip-flop but has two inputs,traditionally labeled J and K. If J and K are different then the output Q takes the value of J at the next clock edge. The inputs are labeled J and K in honor of the inventor of the ...

Daha fazla öğreninStable state implies that the device remains in one state (e.g., 0) until an input changes its condition to the alternative state. Because a flip-flop has two states only, it is called a bi-stable device. A basic flip-flop has two inputs and two outputs, as shown in Figure 1. The two inputs are used to set or reset the device and are denoted by R and S.

Daha fazla öğreninA T flip-flop (Toggle Flip-flop) is a simplified version of JK flip-flop. The T flop is obtained by connecting the J and K inputs together. The flip-flop has one input terminal and clock input. These flip-flops are said to be T flip-flops because of their ability to toggle the input state. Toggle flip-flops are mostly used in counters.
