Question 1

A variable on its own or in its complemented form is known as a

Accepted Answer

A literal in Boolean algebra refers to a variable in either its original form or its complemented form.

Question 2

Canonical form is a unique way of representing

Accepted Answer

Canonical form refers to a standard or unique way of representing Boolean expressions, typically using either the sum of products (SOP) or product of sums (POS) forms, which are derived from minterms and maxterms.

Question 3

There are Minterms for 3 variables (a, b, c).

Accepted Answer

For 3 variables (a, b, c), there are 2^3 = 8 possible combinations of these variables, which means there are 8 minterms.

Question 4

Why is a demultiplexer called a data distributor?

Accepted Answer

A demultiplexer takes a single input and distributes it to one of the several outputs based on a selection signal, effectively distributing data to different destinations.

Question 5

Most demultiplexers facilitate which type of conversion?

Accepted Answer

Demultiplexers convert a single input signal into multiple output signals, effectively distributing the input to one of several outputs.

Question 6

In 1-to-4 demultiplexer, how many select lines are required?

Accepted Answer

A 1-to-4 demultiplexer requires 2 select lines because 2^2 = 4, allowing for the selection of one of four outputs.

Question 7

In 1-to-4 multiplexer, if C1 = 1 & C2 = 1, then the output will be

Accepted Answer

In a 1-to-4 multiplexer, the output lines are typically denoted as y0, y1, y2, and y3. The selection of which output line is active is determined by the combination of the control inputs. Here, C1 and C2 are the control inputs. When C1 = 1 and C2 = 1, the binary representation is '11', which corresponds to the decimal number 3. Therefore, the active output line is y3.

Question 8

How many select lines are required for a 1-to-8 demultiplexer?

Accepted Answer

A 1-to-8 demultiplexer requires 3 select lines because 2^3 = 8, allowing for the selection of one out of eight outputs.

Question 9

How many AND gates are required for a 1-to-8 multiplexer?

Accepted Answer

A 1-to-8 multiplexer requires 8 AND gates, one for each output line, to combine the input with the select lines.

Question 10

Which IC is used for the implementation of 1-to-16 DEMUX?

Accepted Answer

IC 74154 is a 4-line to 16-line decoder/demultiplexer, making it suitable for implementing a 1-to-16 DEMUX.

Question 11

The word demultiplex means

Accepted Answer

The word demultiplex refers to the process of taking a single input signal and routing it to one of many output channels, effectively distributing the signal. It means both "one into many" and acts as a distributor.

Question 12

Why is a demultiplexer called a data distributor?

Accepted Answer

A demultiplexer takes a single input and distributes it to one of the multiple outputs based on a selection or addressing mechanism, effectively distributing data among different paths.

Question 13

In a multiplexer the output depends on its

Accepted Answer

The output of a multiplexer depends on the select inputs, which determine which data input is routed to the output.

Question 14

In 1-to-4 multiplexer, if C1 = 0 & C2 = 1, then the output will be

Accepted Answer

In a 1-to-4 multiplexer, the output lines are selected based on the combination of the select lines. Here, C1 and C2 are the select lines. With C1 = 0 and C2 = 1, the binary combination is '01' which selects output y1.

Question 15

In 1-to-4 multiplexer, if C1 = 1 & C2 = 1, then the output will be

Accepted Answer

In a 1-to-4 multiplexer, the output selected is determined by the combination of the control inputs. Here, C1 and C2 are the control inputs. When C1 = 1 and C2 = 1, the binary combination is '11', which corresponds to the fourth output, y3.

Question 16

What is the addition of the binary numbers 11011011010 and 010100101?

Accepted Answer

The answer of What is the addition of the binary...

Question 17

Perform binary addition: 101101 + 011011 = ?

Accepted Answer

The answer of Perform binary addition: 101101 + 011011 =...

Question 18

Binary subtraction of 100101 - 011110 is

Accepted Answer

Subtracting binary numbers follows the same principle as subtracting decimal numbers but with base 2. Here, we borrow from the next higher bit when needed. The subtraction 100101 - 011110 = 000111 in binary.

Question 19

Perform multiplication of the binary numbers: 01001 × 01011 = ?

Accepted Answer

The binary multiplication of 01001 (9 in decimal) and 01011 (11 in decimal) results in 001100011 (99 in decimal).

Question 20

100101 × 0110 = ?

Accepted Answer

The binary multiplication of 100101 (37 in decimal) and 0110 (6 in decimal) results in 101111110 (222 in decimal).
