An encoder converts an analog signal to a digital signal or encodes information from multiple inputs into an output code. A decoder performs the reverse operation by converting a digital signal to analog or decoding an input code into multiple outputs. Encoders and decoders are used in applications like motor synchronization, robotic vehicles, home automation, and health monitoring where information needs to be encoded for transmission and then decoded at the receiving end.

An encoder (or "simple encoder") in digital electronics is a one-hot to binary
converter. An encoder in digital electronics is an electronic device used to convert
an analogue signal to a digital signal such as a BCD code. It has a number of input
lines, but only one of the inputs is activated at a given time and produces an N-bit
output code that depends on the activated input.

An Encoder is a combinational circuit that performs the reverse operation
of Decoder. It has maximum of 2^n input lines and 'n' output lines, hence it
encodes the information from 2^n inputs into an n-bit code. It will produce a
binary code equivalent to the input, which is active High.

The decoder is an electronic device that is used to convert a digital signal to an
analog signal. It allows a single input line and produces multiple output lines. The
decoders are used in many communication projects that are used to communicate
between two devices. The decoder allows N- inputs and generates 2 power N-
numbers of outputs. For example, if we give 2 inputs that will produce 4 outputs by
using 4 by 2 decoders.

A decoder is a multiple-input, multiple-output combinational logic circuit. It converts
the n bit data inputs into the coded 2n outputs. It decodes the information hidden by
the encoder. While decoding, the decoder generally places a logic 1 at one of its outputs
to create the exact code
