5555555555127. When does the output of a NOR gate = 0? (a) Whenever a 0 is present at an input (b) Only when all inputs = 0 (c) Whenever a 1 is present at an input (d) Only when all inputs = 1
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
