'''Encoder''' may refer to: In this process, we represent the input data meaningfully, which helps someone else to interpret it.

==Electronic circuits==

An '''encoder''' is a [[device]] used to change a [[Signalling (telecommunication)|signal]] (such as a [[bitstream]]) or [[data]] into a [[code]]. The code may serve any of a number of purposes such as compressing information for [[transmission (telecommunications)|transmission]] or [[Computer storage|storage]], [[encrypting]] or adding [[Redundancy (information theory)|redundancies]] to the input code. translating from one code to another. This is usually done by means of a programmed [[algorithm]], especially if any part is [[digital]], while most [[analog (signal)|analog]]ue encoding is done with [[analog circuit|analog circuitry]].

* [[Audio encoder]], converts digital audio to analog audio signals

* [[Video encoder]], converts digital video to analog video signals

* [[Simple encoder]], assigns a binary code to an active input line

* [[Priority encoder]], outputs a binary code representing the highest-priority active input

* [[8b/10b encoding|8b/10b encoder]], creates DC balance on a communication transmission line

==Media compression==

Examples:

* a [[Datadata compression|Compressor]], isencodes useddata to(e.g., encode dataaudio/video/images) into a smaller form. (see [[codec]])

* a [[rotary encoder]] is a sensor or transducer for converting rotary motion or position to a code of electronic pulses.

* a [[multiplexer]] combines multiple inputs into one output.

== Sensors ==

* a [[Data compression|Compressor]] is used to encode data into a smaller form.

* [[id:Encoder (position)]]

** [[Rotary encoder]], converts rotary position to electronic signals

** [[Linear encoder]], converts linear position to electronic signals

** [[Absolute encoder]], outputs the absolute position

** [[Incremental encoder]], converts position changes to electronic signals in real time

* [[Altitude encoder]]
