Decoder is a circuit or we can say its a combinational circuit that is used to decrypt(plain to cipher) the data and also convert binary information to decimal information.
Now I discuss the example of Decoder:-
1)2*4 decoder
Functional Table:-
Logic Circuit:-
2)3*8 decoder(binary to octal)
Functional Table:-
