Design a 4-bit comparator using combinational logic, and Karnaugh Maps. The inputs of
the circuit are two 2-bit numbers.
a) Construct the truth table given 2-bits inputs A and B, and the 3 outputs := {=, >, <}
b) Construct the correct K-Map
c) (10 pts) Apply the K-Map to the minterms
d) Apply the K-Map to the maxterms
e) Prove that the expressions found on c and d are equal
f) Construct the resulting circuit
