When both inputs of a J-K flip-flop cycle, the output will ___________(a) Be invalid(b) Change(c) Not change(d) ToggleThe question was asked in my homework.This question is from Flip Flops topic in section Flip-Flops of Digital Circuits

Answer»

Correct choice is (c) Not change

Explanation: After one cycle the value of each input comes to the same value. Eg: Assume J=0 and K=1. After 1 cycle, it becomes as J=0->1->0(1 cycle COMPLETE) and K=1->0->1(1 cycle complete). The J & K flip-flop has 4 STABLE states: Latch, Reset, SET and TOGGLE.
