Q. |
When both inputs of a J-K flip-flop cycle, the output will |
A. | be invalid |
B. | change |
C. | not change |
D. | toggle |
Answer» 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. |
