Question

Assume the initial status of below circuit is ABC-000. What is the status after three clocks? TLI

Please explain in details, thanks!

Answer 1

initial status of circuit is ABC = 000. What is the status after three clocks. Given circuit is synchronous, because same clock is connected to all flipflops. given D, T, J-K flipflops connected together simultaneously. First clock for next state of A, input of D is output of C in initial state i. e, 0. 0 input given to D flipflop: output A is 0. for next state of B, input of T flipflop is output of complement of A in initial state i. e, 1 1 input given to T flipflop, it toggles, i. e, gives output as complement of previous state value of B. i. e, 1 \r\n for next state C, input of J-K is for J, previous state value of B is input i. e, 0 for K, previous state complement value of A is input i. e, 1. For J = 0, K = 1 output of C is 0.
