what is the minimum size of multiplexers necessary to implement a boolean function of 5 variables?

Answer = _____ to 1 line mux

Step 1

A multiplexer is a combinational circuit that selects binary information from one of many input lines and directs it to a single output line.

The selection of a particular input line is controlled by a set of selection lines. Generally, there are 2^{n} input lines and n selection lines whose bit combinations determine which input is selected.

Step 2

In case of minimum size, for n variable function a data selector with (n-1) select inputs and 2^{n-1} data inputs required. So, the minimum size of multiplexer needed is 2^{n-1} line to 1 line.

Step 3

According to the question, for 5 variables (5-1) that is 4 select inputs and 24 data inputs requir...
