Using a one-bit full adder as a building block, draw a circuit that performs addition of two 3-bit twos complement numbers named N and P. (Remember: The three bits of N are N[0], N[1], and N[2]. N[0] is the least significant bit.) The sum (output) is a three-bit 2C number named T. (You dont need to draw the internal gates inside the full adder. Draw the adder as a box, as shown below.) Make sure all signals are labeled.
