Assignment 2 Solutions

Background: Consider the hexadecimal numbers EE9CA0 and 053977.
a) Convert each of these numbers to a 24-bit binary number. (0.5 points)

EE9CA0 = 111011101001110010100000 053977 = 000001010011100101110111

b) Convert each of these numbers to an 8-digit octal number. (0.5 points)

EE9CA0 = 73516240 053977 = 01234567
Background: Consider the following 2 10-bit binary numbers: 1110110101 0011011000
a) Give the one's complement of each of these numbers. (0.2 points)

1110110101 = 0001001010 0011011000 = 1100100111

b) Give the two's complement of each of these numbers. (0.2 points)

1110110101 = 0001001011 0011011000 = 1100101000

c) Assuming that each of these numbers is an unsigned binary number, give the decimal equivalent. (0.2 points)

1110110101 = 949 0011011000 = 216

d) Assuming that each of these numbers is in the one's complement number system, give the signed decimal equivalent. (0.2 points)

1110110101 = -74 0011011000 = 216

e) Assuming that each of these numbers is in the two's complement number system, give the signed decimal equivalent. (0.2 points)

1110110101 = -75 0011011000 = 216
