Answer 2

Answer:

1100

Explanation:

Given- (9)10

To find- Excess code of (9)10

Before solving we should know about the excess -3 code. It can be defined as follows

Excess -3 is a digital code obtained from adding 3 to every decimal digit and after that converting the result to 4 bit binary number.

We have 9 as the decimal no so we will add 3 in it

9+3=12

Now we have to convert 12 into binary number.

12÷2= 6 Remainder 0

6÷2= 3 Remainder 0

3÷2= 1 Remainder 1

1÷2= 0 Remainder 1

So Binary number for 12 is 1100

Ans= Excess -3 code for (9)10 is 1100
