How many 2 input mux required construct 210 input mux?

Answer 1

To construct a 210-input multiplexer (mux) using 2-input multiplexers, you can use a binary tree structure. The number of 2-input muxes required is calculated as follows: you need 209 2-input muxes to combine 210 inputs into a single output. This is because each mux combines two inputs, and you continue combining until all inputs are reduced to one final output.
