Simple encoder
An encoder (or "simple encoder") in digital electronics is a one-hot to binary converter. That is, if there are 2''n'' input lines, and at most only one of them will ever be high, the binary code of this 'hot' line is produced on the ''n''-bit ou ...
, assigns a binary code to an active input line
*
Priority encoder A priority encoder is a circuit or algorithm that compresses multiple binary inputs into a smaller number of outputs. The output of a priority encoder is the binary representation of the index of the most significant activated line, starting from ...
, outputs a binary code representing the highest-priority active input

Compressor
A compressor is a mechanical device that increases the pressure of a gas by reducing its volume. An air compressor is a specific type of gas compressor.
Compressors are similar to pumps: both increase the pressure on a fluid and both can transp ...
, encodes data (e.g., audio/video/images) into a smaller form (see

Rotary encoder
A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to analog or digital output signals.
There are two main types of rotary encoder: absolute and increme ...
, converts rotary position to electronic signals
**
Linear encoder, converts linear position to electronic signals
**
Absolute encoder
A rotary encoder, also called a shaft encoder, is an electro-mechanical device that converts the angular position or motion of a shaft or axle to analog or digital output signals.
There are two main types of rotary encoder: absolute and increm ...
, outputs the absolute position
**
Incremental encoder, converts position changes to electronic signals in real time

Altitude encoder
Gillham code is a zero-padded 12-bit binary code using a parallel nine- to eleven-wire interface, the Gillham interface, that is used to transmit uncorrected barometric altitude between an encoding altimeter or analog air data computer and a di ...
