Magnitude Comparator: Combinational circuit that compares two numbers and determines their relative magnitudes. For example given two numbers A and B we want to determine if A > B A < B A = B We may have a temperature sensor in a server room that is providing digital data (B) to a monitoring circuit. The number A may Represent an upper limit, then if A > B do nothing A = B do nothing A < B sound the alarm!

Do you really want to do it this way?
