Using Full Adders and other logic gates, design a digital circuit that will input two 4-bit binary two's complement numbers and outputs a 5-bit binary number that will Subtract the two input numbers and determines if an overflow occurred. For example: if the inputs are (0110) and (0011), then your digital circuit would perform 0110 - 0011 = 0110 + (1100 +0001) = 0110 + 1101= 0011, so that the output is 00011 and the Overflow bit is 0. You must show the logic for determining the Overflow bit value.
