Unformatted text preview: a) obtain the binary presentation for the following negative decimal number: - 6 10 = 11111010 starting with +6: 00000110 1s complementing by inversion of all bits: 11111001 + ______ 1 2s complement by incrementing the 1s complement: 11111010 b) determine both sign and magnitude of the binary number presented as follows 11111010 2 = -6 10 MSB = 1 indicates that the sign is negative. Thus, the number is presented in the 2s complement form. In this case the binary magnitude is obtained by 2s finding a 2s complement of the number in the 2s complement form. 11111010 1s complement by bit inversion 00000101 2s complement by incrementing the 1s complement 00000110 = 6...
