Question

I am trying to find out a design containing NOR and OR or AND gate for the interface block design. I have completed a design for when A = B, but I am having difficulty designing A < B and B > A on the subtractor where the boxes have question marks. Please help!

8.3* The circuit of 8.2, configured as a subtractor, can be used to compare two 4-bit numbers. Subtractor outputs C4 and (S3..S0) can be combined logically to indicate the relationship between inputs A and B. The gate circuit needed to do this appears as the interface block in the following diagram Subtractor to LEDs 4 Interface Block 4 S3 S2 S1 So 4 (your design) "A> B" (A - B) Design the contents of this interface. You will build the circuit using only 2 chips 1. a 7402 NOR chip 2. either a 7432 OR chip or a 7408 AND chip.
