Q. Illustrate the working of FLIP-FLOPS?
A flip-flop is a binary cell that stores 1-bit of information. It itself is a sequential circuit. We know that flip-flop can change its state when clock pulse happens but when? Normally a flip-flop can alter its state when clocks transitions from 0 to 1 (rising edge) or from 1 to 0 (falling edge) and not when clock is 1. If storage element alters its state when clock is exactly at 1 then it is known as latch. In other words flip-flop is edge-triggered whereas latch is level- triggered.
