S-R Flip-Flop
After I search on the internet and read many, I finally know how SR Flip-Flop works! The online and book explanation like High level IQ Quizz for me, thus I try to simplify it and I assume you know what is flip-flop. S‑R flip‑flop has 2 inputs, S (set) and R (reset) and 2 output,Qn ,Qn+1 .In the diagram above, (also for JK and D flip-flops), they used another input called clock. It is to control the movement of input that is input will only occur when given a clock pulse (synchronous circuit). Before I start to explain how it work! Read the details below! Q n = present state/condition Q n+1 = next state/condition If the input of S and R is 0 then the Output(Q n+1 ) will remain it state at Qn! If the input of S is 0, while R is 1's, the output(Q n+1 ) will become 0. if the input of S is 1 while R is zero, the output(Q n+1 ) will become 1. The input of S and R cannot both is 1's. May be you think it was too simple, yes is it. Just don't kn...
