2. a) Perform the following subtraction operations by using 1's and 2's complements separately. Show the sign and magnitude of the result. (Numbers are unsigned). 1010 – 0111; 0110 – 1100 b) Perform the following operations first by representing the numbers in signed 2's complement form with 5 bits (1 bit for sign and 4 for magnitude) and then adding. Interpret the results in terms of sign and magnitude. 101 + 011; (-100) + 110; 1010 + 1100; (-1000) + (–1010) For cases where overflow occurs increase number of bits to 6 and repeat operations. Verify that this time result is correct. c) Represent the decimal numbers +310 and -540 in signed 10's complement form with 4 digits. Write BCD representation for each number. Add them by using BCD addition and write the actual magnitude and sign of the result as a decimal number.
