Difference Between SR Flip – flop and RS Flip – flop
The flip-flop is nothing but a term that lies under digital electronics which is an electronic component that is used to store one bit of information.
As we know Flip Flop is a sequential circuit, its input is based upon two parameters named as the current input and the output from the previous state. It has two outputs; both are complements of each other. It may be in one of two stable states, either 0 or 1.
In this article, we will study the difference between SR and RS flip-flops.
