3- to-8 line Decoder full Block Diagram, Truth Table, and Logic Diagram

 What is  a Decoder:

         A decoder is used to convert binary into decimal. Decoder is a combinational logic circuit that has n input lines and a maximum of 2n unique output lines.

3-to-8 Line Decoder:

               A 3x8 lines decoder has three inputs  i.e A,B,C and eight outputs i.e D0 ,D1,D2,D3,D4,D5,D6 and  D7. which are generated by using inputs i.e 2^3.
