The truth table of the following circuit is

Which of the following logic gates is called a Universal gate?

The resultant logic gate from the combination of the following gates is:

Match the following List $I$ and List $II$.

$A$. Small Scale Integration $(SSI)$	$I$. Logic gates $< 100$
$B$. Medium Scale Integration $(MSI)$	$II$. Logic gates $> 1000$
$C$. Large Scale Integration $(LSI)$	$III$. Logic gates $\leq 10$
$D$. Very Large Scale Integration $(VLSI)$	$IV$. Logic gates $< 1000$

Which of the following represents a universal gate?

$A$ person applies a sine wave and a square wave to an $AND$ gate as shown in figures $(i)$ and $(ii)$. Assuming that both the voltages are applied in phase, the person observes the output at $E$ and $F$ on $(i)$ and $(ii)$, respectively. [Assume a minimum voltage of $5 \ V$ is equivalent to logic $1$].
