Test: Multiplexers - Question 1

What is a multiplexer?

Detailed Solution for Test: 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: Multiplexers - Question 2

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: Multiplexers - Question 2

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: Multiplexers - Question 3

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

Detailed Solution for Test: Multiplexers - Question 3

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: Multiplexers - Question 4

A digital multiplexer is a combinational circuit that selects ___________

Detailed Solution for Test: Multiplexers - Question 4

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: Multiplexers - Question 5

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

Detailed Solution for Test: Multiplexers - Question 5

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

Test: Multiplexers - Question 6

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

Detailed Solution for Test: Multiplexers - Question 6

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.

Test: Multiplexers - Question 7

The enable input is also known as ___________

Detailed Solution for Test: Multiplexers - Question 7

The enable input is also known as strobe which is used to cascade two or more multiplexer ICs to construct a multiplexer with a larger number of inputs. Enable input activates the multiplexer to operate.

Test: Multiplexers - Question 8

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

Detailed Solution for Test: Multiplexers - Question 8

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: Multiplexers - Question 9

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

Detailed Solution for Test: Multiplexers - Question 9

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: Multiplexers - Question 10

One multiplexer can take the place of ___________

Detailed Solution for Test: Multiplexers - Question 10

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.
