Question 176: Semiconductors and Logic Gates

Question

The logic circuit shown below has the input waveforms $$'A'$$ and $$'B'$$ as shown. Pick out the correct output waveform.

Output is

Accepted Answer

Here $$y = \overline {\left( {\overline A  + \overline B } \right)}  = \overline {\overline A } .\overline {\overline B }  = A.B.$$
Thus it is an $$AND$$ gate for which truth table is
