Design a combinational logic circuit that converts a 4 bit sign-magnitude number to the corresponding 4 bit 2's complement representation. write down the minimized expressions for a+,b+,c+ and d+ in order. a and a+ represent sign bit; b and b+, c and c+ and d and d+ represent magnitude bits from the most-significant bit to the least significant bit in each of their representation (sign bit-magnitude and twos' complement respectively).
