Question 1

What is the output Y in the following circuit when all the three inputs A, B, C are first $0$ and then $1$?

Accepted Answer

Here the gate P is a logic symbol of AND gate and Q is a NAND gate.So, the output of P is $Y_p=A.B$ and the output of Q is $ Y=\bar{Y_p.C}$When $A=0, B=0, C=0 \Rightarrow Y_p=0 , Y=\bar{0.0}=1$When $A=1, B=1, C=1 \Rightarrow Y_p=1 , Y=\bar{1.1}=0$

Question 2

Two following figure shows a logic gate circuit with two inputs A and B and the output Y. The voltage wave forms of A, B and Y are as given.The logic gate is

Accepted Answer

It is clear from given logic circuit, that output Y is low when both the inputs are high, otherwise it is high. Thus, logic circuit is NAND gate.ABY1   1000101   1101

Question 3

To get output $1$ for the following circuit, the correct choice for the input is.

Accepted Answer

From left side the first gate is OR gate and next one is AND gate. So the out put of OR gate  is $A+B$ and the output of AND gate $Y=(A+B).C$We know that  for AND gate the put will be 1 if both inputs are 1. So, $A+B =1 $and $C=1$In logic gate , $ 1+0=1$ so $A=1,  B=0 , C=1 $ will be the correct choice for output 1.

Question 4

The output (X) of the logic circuit shown in the figure will be

Accepted Answer

$X=\bar{\bar{AB}}=A.B$

Question 5

Which logic gate is represented by the following combination of logic gates?

Accepted Answer

A B Y0  0 00  1  01  0  01   1   1AND gate.

Question 6

The increase in the width of the depletion region in a p-n junction diode is due to :

Accepted Answer

The increase in the width of the depletion region is due to the absence of the electrons and holes in the region. This occurs only in the case of the reverse bias only in a diode.

Question 7

The given electrical network is equivalent to:

Accepted Answer

If we put input as A=0 B= 0 then we are get out put as F=1In similar way the following shown in the table are also true. The resulting table is nothing but the truth table of NOR gate. Hence option D is the correct answer.
