Load the circuit file for Section 6-4. This is a Parallel Binary Comparator similar to Figure 6-14. Two 4-bit binary strings are provided by the Word Generator.
(a) What type of Word Generator numbers turn the light ON?
(b) Let's say that when you go to build the circuit in lab, you can't find any Ex-NORs but have four Ex-ORs. To get the same circuit function, what must the AND gate be changed to? Try it.
