Q1. Design a Xor gate using 4:1 mux?
Ans. 
Xor gate can be designed using 4:1 mux by selecting inputs based on control signals.
• Use 4:1 mux with two inputs as A and B, one input as A' and one input as B'.

• Connect A and B to select lines of mux.

• Connect A' and B' to the data inputs of mux.

• Set control signals such that when A=0, B=1 or A=1, B=0, the output is 1.

• When A=B=0 or A=B=1, the output should be 0.
