Question

The output waveform of the given logical circuit for the following inputs A and B as shown below, is

TestHub · Accepted Answer

In the given logical circuit, all logic gates are NAND gate.

Here, the inputs $A$ and $B$ are inverted using NOT gate (made using NAND gate), then $\bar{A}$ and $\bar{B}$ are applied as inputs in other NAND gate.

So, $(A . A) = A$ and $B . B = B$

Output at $Y$ is $(A . B) = A + B$ .

The above boolean expression is for OR gate.

Truth table of OR gate is

$A$	$B$	$Y$
$0$	$0$	$0$
$0$	$1$	$1$
$1$	$0$	$1$
$1$	$1$	$1$

The output waveform is shown below.
