Question 182: 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
