2. The Value obtained after complementing is binary 0011
3. Binary 0011 in decimal value is 3
4. Add the decimal value 48 to 3 will give 51
5. The decimal value 51 in ASCII character is “3”
ExampleTo decompress the value of data received which is “±”
Step 1. The decimal value for “±” is 216 or a Binary value of 11011000
