I don't know..You may be right..i was asking you :P

if my approach is wrong then the solution which is given below will also wrong.

Answer 1

To convert a decimal no. to  2421 weighted code, do as follows:

Ex: 4 can be 2x0+4x1+2x0+1x0 here 4 is 0100

Any number > 4 has msb 1 whereas < 4 msb 0. It is known as self complementary bcz to get a number > 4 take 9's complement.

1 --  0 0 0 1

2 --  0 0 1 0

3 --  0 0 1 1

4 --  0 1 0 0

5 -- 9's complememt of 4 = 1 0 1 1

6 -- 1 1 0 0

7  -- 1 1 0 1

8 -- 1 1 1 0

9 -- 1 1 1 1
thus, 1234 in decimal can be written as 0001001000110100 in 2421 weighted code
