The output of the circuit is low (zero) for: $(A) \ X = 0, Y = 0$,$(B) \ X = 0, Y = 1$,$(C) \ X = 1, Y = 0$,$(D) \ X = 1, Y = 1$. Choose the correct answer from the options given below:

Which logic gate is represented by the following truth table?

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

In the given circuit as shown,two input waveforms $A$ and $B$ are applied simultaneously. The resultant waveform $Y$ is:

Digital signals are characterized by which of the following statements?
$(i)$ They do not provide continuous values.
$(ii)$ They represent values in discrete steps.
$(iii)$ They can be represented by a binary system.
$(iv)$ They represent both binary and decimal systems.

In the given logic circuit diagram,$A$,$B$,and $C$ are the inputs,and $Y$ is the output. The output $Y$ is ' $HIGH$ ' (i.e.,$Y=1$):
