Realize a BCD to excess3 code converter using a 4to 10 decod

Realize a BCD to excess-3 code converter using a 4-to- 10 decoder with active low outputs and a minimum number of gates.

Solution

Answer :

Realize a BCD to excess-3 code converter using a 4-to-10 decoder with active low outputs and a minimum number of gates?

Answer :

1.Four NAND gates are needed,and each has 5 inputs

   2.Because the excess-3 outputs are

                       m(5,6,7,8,9),m(1,2,3,4,9),m(0,3,4,7,8),& m(0,2,4,6,8)
