The input signals A and B to a NOR gate are provided as digital voltage waveforms. Over four consecutive equal time intervals, the logic levels of input A are 0, 1, 0, 1 and those of input B are 0, 0, 1, 1 . The corresponding logic levels of the output waveform Y over the same four time intervals will be:

Step-by-step solution

The logic gate given is a NOR gate. The Boolean expression for a NOR gate is Y = A + B . Let us evaluate the output Y for each time interval: Interval 1: A = 0, B = 0 Y = 0 + 0 = 0 = 1 Interval 2: A = 1, B = 0 Y = 1 + 0 = 1 = 0 Interval 3: A = 0, B = 1 Y = 0 + 1 = 1 = 0 Interval 4: A = 1, B = 1 Y = 1 + 1 = 1 = 0 Thus, the sequence of logic levels for the output Y is 1, 0, 0, 0 . Answer: 1, 0, 0, 0
