A 4-bit binary code converter is a circuit that can convert a 4-bit binary code represent from one form to another. The excess-3 code (or XS3) is a non-weighted code used to express code used to ...

Decimal numbers between 100 and 109 would be represented in BCD by the actual number + 156 (26*6). Numbers between 110 and 119 convert to BCD values of the actual number + 156 + 6.

Finally, the reversible design of the BCD adder is presented which is based on a 4 bit reversible binary adder to add the BCD number, and finally the conversion of the binary result to the BCD format ...
