(d) Both (a) and (b)
5555555555139. The inputs on a 7474 D flip-flop are S, R, D, and CLK ________ is/are synchronous. (a) Only S (b) S and R (c) Only D (d) All of the above. 555555555567. Why are the S and R inputs of a gated flip-flop said to be synchronous? (a) They must occur with the gate. (b) Th (c) (d) 5555555555147. When the output of the NOR gate S-R flip-flop is Q = 0 and , the inputs are: (a) S = 1, R = 1 (b) S = 1, R = 0 (c) S = 0, R = 1 (d) S = 0, R = 0 Flip-Flops » Exercise - 124.
