Design a digital circuit with three inputs x, y, z and three outputs A, B, C
When the binary input is 0, 1, 2, or 3, the binary output is one greater than the input.
When the binary input is 4, 5,6, or 7 the binary output is two less than the input
Design a four bit circuit 2’s complementer. (The output is the 2’s complement of the input)
