Overview: Understanding a 2’s complement 4 bit adder circuit
Resources to consult: Digital Electronics: Principles and Applications, 8th Edition, Chapter 10
Instructions:
1.Construct a 4 bit 2’s complement adder circuit using discrete components (and, or, xor etc)
2.Display the result on 2 seven segment displays, one for sign and one for number
3.If the number if positive, use BCD to seven segment to display output
4.If the number is negative, invert every signal, use another 4 bit adder and add a one, then use a BCD to seven segment to display output
5.Describe operation of the circuit. Capture output of seven segment for max, min and in between values
