Question

With the help of an example explain 1’ complement and 2’ complements.

Answer 1

*1’ complement:**

Representing a signed number with 1’ complement is done by changing all the bits that are 1 to 0 and all the bits that are 0 to For example, 1’ complement of 1010100 is 0101011.

*2’ complement:**

Representing a signed number with 2’ complement is done by adding 1 to the 1’ complement representation of the number. For example, 2’* complement of 1010100 is

• Step 1: 1’* complement of 1010100 is 0101011
• Step 2: add
