Define multiplexer. Implement 8 × 1 multiplexer using 2 × 1 multiplexer. [1+4]

A multiplexer (MUX) is a combinational circuit that selects one of many input lines and forwards it to a single output line based on select lines. It is also called a data selector. - An n-input multiplexer has: - 2^n data input lines - n select lines - 1 output line --- - An 8×1 MUX has: 8 data ...
