Question

Encoder and decoder in basic communication

Answer 1

Decoder
In digital electronics, a decoder can take the form of a multiple-input, multiple-output logic circuit that converts coded inputs into coded outputs, where the input and output codes are different e.g. n-to-2n , binary-coded decimal decoders. Decoding is necessary in applications such as data multiplexing, 7 segment display and memory address decoding.
Encoder
An encoder is a device, circuit, transducer, software program, algorithm or person that converts information from one format or code to another. The purpose of encoder is standardization, speed, secrecy, security, or saving space by shrinking size. Encoders are combinational logic circuits and they are exactly opposite of decoders. They accept one or more inputs and generate a multibit output code.

Answer 2

The enco der should also take into account any 'noise' that might interfere with their message, such as other messages, distractions, or influences. The audience then 'deco des', or interprets, the mes.sage for themselves. Deco ding is the process of turning communication into thoughts.
