Single logic gate does not have any information storing capacity but by combining different such gates one can make such a digital circuit which can store digital information. The frequency of oscillation depends on the time constant of r and c, but is also affected by the. The flip flop is a basic building block of sequential logic circuits. Flip flop is an important basic memory element for digital circuit. Flipflop is designed by assembling different logic gates. Flipflops are a useful type of digital device that can store binary states, or be used as a sort of digital toggle switch. Such a circuit can deal with a sequence of digital events, and is therefore known as sequential logic. Frequently additional gates are added for control of the. Flops more so than latches, since they hold their output value while the input is unstable between clock pulses. Adding a clocking input to control the timing of the nand latch. The effect of the clock is to define discrete time intervals. In this lesson we take a look at two types of the flipflops, the jk and d flipflops.
Figure 8 shows the schematic diagram of master sloave jk flip flop. In digital circuits, the flipflop is a kind flipflop, of bistable multivibrator.
