Explain about Flip-Flops
Flip-Flops are also called bistable multivibrator. A flip-flop is capable of storing 1 bit of binary data. It has two stable states- 'one' and 'zero'. The output stays low or high, to alter it, the circuit must be drived by an input called trigger. Unless the trigger arrives, the output voltage remains low or high indefinitely. Edge Triggered Flip-flops:- An edge triggered flip-flop responds only during the brief instant the clock switches from one voltage level to another. When the triggering happens on the positive going edge of the clock, it is known as positive-edge triggering. Sometimes, triggering on the negative edge is better suited to the application. This means the trailing edge of the clock activates the gates, permitting data to be recognized. This is called negative-edge triggering.
