Concept:
1’s complement representation of a binary number is obtained by toggling all the bits, i.e. replacing 1 with 0, and 0 with 1.
2’s complement representation of a binary number is obtained by adding 1 to the 1’s complement representation.
Application:
Given the binary number is 1101101
Taking the 1's complement of the above, we replace all the 1's with 0's and all the 0's with 1's to get:
1's complement of 1101101 = 0010010
Adding 1 to the 1's complement, we get the 2's complement as:
0010010 + 1 = 0010011
