Answer 2

There are three data select lines that are required for selecting eight inputs.

• The data select lines are required for the multiplexer. For eight inputs, we have three data select lines, and it is an 8:1 multiplexer.

What is a multiplexer? Write its advantage?

• When we study electronics, there is a device that selects digital or analog signals as inputs and puts forward that selected inputs to one signal as an output, this type of device, is known as a multiplexer or commonly called mux.
• The advantage of using a multiplexer is that we can transfer the inputs of a large number of signals into a single entity or medium.
