CS 151: Digital Design

CS 151: Digital Design . Chapter 3 3-8: Encoding. Encoding. Encoding - the opposite of decoding - the conversion of a maximum of 2 n input code to an n -bit output code such that each valid code word produces a unique output code. Circuits that perform encoding are called encoders.
