Test: Data Selectors & Multiplexers - Question 1

What is a multiplexer?

Detailed Solution for Test: Data Selectors & Multiplexers - Question 1

A multiplexer (or MUX) is a device that selects one of several analog or digital input signals and forwards the selected input into a single line, depending on the active select lines.

Test: Data Selectors & Multiplexers - Question 2

Which combinational circuit is renowned for selecting a single input from multiple inputs & directing the binary information to output line?

Detailed Solution for Test: Data Selectors & Multiplexers - Question 2

Data Selector is another name of Multiplexer. A multiplexer (or MUX) is a device that selects one of several analog or digital input signals and forwards the selected input into a single line, depending on the active select lines.

Test: Data Selectors & Multiplexers - Question 3

It is possible for an enable or strobe input to undergo an expansion of two or more MUX ICs to the digital multiplexer with the proficiency of large number of ___________

Detailed Solution for Test: Data Selectors & Multiplexers - Question 3

It is possible for an enable or strobe input to undergo an expansion of two or more MUX ICs to the digital multiplexer with the proficiency of large number of inputs.

Test: Data Selectors & Multiplexers - Question 4

Which is the major functioning responsibility of the multiplexing combinational circuit?

Detailed Solution for Test: Data Selectors & Multiplexers - Question 4

The major functioning responsibility of the multiplexing combinational circuit is generation of selected path between multiple sources and a single destination because it makes the circuit too flexible. A multiplexer (or MUX) is a device that selects one of several analog or digital input signals and forwards the selected input into a single line, depending on the active select lines.

Test: Data Selectors & Multiplexers - Question 5

What is the function of an enable input on a multiplexer chip?

Detailed Solution for Test: Data Selectors & Multiplexers - Question 5

Enable input is used to active the chip, when enable is high the chip works (ACTIVE), when enable is low the chip does not work (MEMORY). However, Enable can be Active-High or Active-Low, indicating it is active either when it is connected to VCC or GND respectively.

Test: Data Selectors & Multiplexers - Question 6

One multiplexer can take the place of ___________

Detailed Solution for Test: Data Selectors & Multiplexers - Question 6

A multiplexer (or MUX) is a device that selects one of several analog or digital input signals and forwards the selected input into a single line, depending on the active select lines. Since many operational behaviour can be performed by using a multiplexer. Whereas, a combinational circuit is a combination of many logic gates which makes the circuit more complex.

Test: Data Selectors & Multiplexers - Question 7

A digital multiplexer is a combinational circuit that selects ___________

Detailed Solution for Test: Data Selectors & Multiplexers - Question 7

A digital multiplexer is a combinational circuit that selects one digital information from several sources and transmits the selected information on a single output line depending on the status of the select lines. That is why it is also known as a data selector.

Test: Data Selectors & Multiplexers - Question 8

In a multiplexer, the selection of a particular input line is controlled by ___________

Detailed Solution for Test: Data Selectors & Multiplexers - Question 8

The selection of a particular input line is controlled by a set of selected lines in a multiplexer, which helps to select a particular input from several sources.

Test: Data Selectors & Multiplexers - Question 9

If the number of n selected input lines is equal to 2^m then it requires _____ select lines.

Detailed Solution for Test: Data Selectors & Multiplexers - Question 9

If the number of n selected input lines is equal to 2^m then it requires m select lines to select one of m select lines.

Test: Data Selectors & Multiplexers - Question 10

A basic multiplexer principle can be demonstrated through the use of a ___________

Detailed Solution for Test: Data Selectors & Multiplexers - Question 10

A basic multiplexer principle can be demonstrated through the use of a rotary switch. Since its behaviour is similar to the multiplexer. There are around 10 digits out of which one is selected one at a time and fed to the output.
