A parity checker will be designed with $2$ LEOs. IED O Indicating odd parity and LED E indicating even parity.

If number of $"1"$s in an incoming $3-$bit bit stream is an odd number LED $O$ will be on;

If number of $"1"$s in an incoming $3-$bit bit stream is an even number LED $E$ will be on

Implement this circuit using $4$:$1$ multiplexers.
