They also have the same truth tables, but they are flipped. For example, the truth table of a 2-to-4 decoder is the same as the truth table of a 4-to-2 encoder, but with the rows and columns swapped.

This paper describes the system implemented in “Kovcheg” CAD for integrated circuit design automation. This system allows the user to specify combinational circuits in the form of truth tables. Truth ...

The combinational circuits that change the binary information into N output lines are known as Encoders. The binary information is passed in the form of 2N input lines. Encoder performs the reverse ...
