Question: Draw the truth table for the adder having A, B, C, D as inputs and X, Y, Z as outputs.
A B
+C D
=XYZ
Here X is equivalent to Cout.
Q: Design a circuit to implement the truth table using Decoder (1-4 to 16 decoder or 2-3 to 8 decoder) and logic gates (not necessarily 2 I/P's).
Find the integrated circuit part numbers that will allow you to implement these functions and when you realize these circuits at the similar time what do you expect the result to be?
Verify your solution using truth tables.
