Question

Design a digital circuit that takes two 2-bit numbers a and b as input and generates output z as follows: if a and b are odd numbers then z=a-b if a and b are even numbers then z=b-a if a is an even number and b is an odd number then z=a+b if a is an odd number and b is an even number then z=a b-1 assume that you have access to 4 * 1 mux.
