A half subtractor subtracts two bits, x and y producing their difference d. It also has an output b to specify if a 1 has been borrowed from the next higher position. The truth table is given below. Draw the "Half Subtractor" circuit, then, test the truth table. Write the Boolean function for d and b beside the circuit. Hand-In - The the "Half Subtractor " Circuit. Boolean functions for borrow (b) and difference (d)
