Circuit Design - Problem 4

Design and implement a digital circuit that takes three inputs A, B, and C and outputs a value of 1 whenever the arithmetic expression A + B = C is true. The inputs must be named A, B, and C, and there must be only one output.

Hint: The work area is too small to solve this problem with a "bull-at-the-gate" solution to this problem; you have to find a way to reduce the number of gates needed.

Resize and reposition this window so that you can refer to it easily while you are implementing the circuit on the other page.
