Encoder is a circuit or we can say its a combinational circuit that is used to encrypt(cipher to plain) the data and also convert decimal information to binary information.It is totally reverse to Decoder.
Now I discuss the examples of Encoder:-
1)4*2 decoder
Functional Table:-
D(1)=I(2)+I(3)
D(0)=I(1)+I(3)
2)10*2 encoder or Decimal to binary encoder
D(3)=I(8)+I(9)
D(2)=I(5)+I(6)+I(4)+I(7)
D(1)=I(2)+I(3)+I(6)+I(7)
D(0)=I(1)+I(3)+I(5)+I(7)+I(9)
Now I discuss the examples of Encoder:-
1)4*2 decoder
Functional Table:-
| I(0) | I(1) | I(2) | I(3) | D(1) | D(o) |
|---|---|---|---|---|---|
| 1 | 0 | 0 | 0 | 0 | 0 |
| 0 | 1 | 0 | 0 | 0 | 1 |
| 0 | 0 | 1 | 0 | 1 | 0 |
| 0 | 0 | 0 | 1 | 1 | 1 |
D(1)=I(2)+I(3)
D(0)=I(1)+I(3)
2)10*2 encoder or Decimal to binary encoder
| I(0) | I(1) | I(2) |

D(3)=I(8)+I(9)
D(2)=I(5)+I(6)+I(4)+I(7)
D(1)=I(2)+I(3)+I(6)+I(7)
D(0)=I(1)+I(3)+I(5)+I(7)+I(9)
