In a NAND gate the input signals are X and Y and the output signal is Z. If the inputs X and Y have the following pulse patterns
then the output Z will be
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
For a NAND gate:
So the output Z is LOW (0) only when both X and Y are HIGH (1).
For all other combinations, 
.
From the given pulse patterns, there are three intervals where 
and 
simultaneously. Therefore, the NAND output remains HIGH most of the time and shows three LOW pulses at those intervals.
