The sign changer is a combinational circuit that has two inputs

i) an 8-bit bus A[7:0] representing a number in two's complement, and

ii) a 1-bit input sign specifies whether the number's sign should be changed.

1) In this problem, you will supply values for SignChanger that satisfy specific conditions

a)

b)

Give a value in hex for A that causes 4 different hex digits to be displayed by varying the value of sign. A= Give another value in hex for A that causes 4 different hex digits, different from the previous question, to be displayed by varying the value of sign. A=
