Unformatted text preview: 1's complement of (110110) is (001001) 1's complement of (100000.011) is (011111.100) 2. 110110 – 011101 Æ 110110 + 100011 = 1011001 Discard the end carry. Answer is 011001 3. 75 in binary is 1001011, then +75 using 8 bits is 01001011 52 in binary is 110100, then +52 using 8 bits is 00110100 and -52 is 11001100 (+75) + (-52) is 01001011 11001100 100010111 Æ discard end carry, result is + 23 4. 482.5 Æ BCD 0100 1000 0010 . 0101 2421 0100 1110 0010 . 1011 5. " Home Work 2 is due " is represented in ASII using Hexadecimal representation is: 48 6F 6D 65 20 57 6F 72 6B 20 32 20 69 73 20 64 75 65...
