Q1:

The following waveform pattern is for a(n) ________.

A 2-input AND gate

B 2-input OR gate

C Exclusive-OR gate

D None of the above

ANS:C - Exclusive-OR gate

Exclusive OR means either of the Inputs(A or B) is high then the output (X) will be high otherwise X will be low. So waveform satisfies this condition. If both i/p high or both i/p are low then o/p will be low. So, one i/p should be low and other should be high or vice versa for being o/p high.
