Load the circuit file for Section 8-1a. This is a binary comparator similar to Figure 8-1. Test its operation by observing the Equality Indicator status for various 4-bit inputs at the A-inputs and B-inputs.
(a) What input conditions are required for the indicator to come ON?
(b) Redesign the circuit using ex-ORs instead of ex-NORs. What must the AND gate be changed to to get the same output result? Test your design with several different input combinations.
