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

[[Image:Encoder_Example.svg|thumb|right|Example: A Single Bit 4-to-2 Line Encoder]]An '''encoder''' is a [[device]] used to encode a [[Signalling (telecommunication)|signal]] (such as a [[bitstream]]) or [[data]] into a form that is acceptable for [[transmission (telecommunications)|transmission]] or [[Computer storage|storage]]. 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]]ry.

==Electronic circuits==

:''A [[rotary encoder]] is a sensor or transducer for converting rotary motion or position to a series of electronic pulses.''

* [[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==

:''Likewise, a linear encoder is a sensor or transducer for converting linear motion or position to a series of electronic pulses. Linear encoder technologies include capacitive, inductive, eddy current, magnetic, and optical. Optical technologies include shadow, self imaging and interferometric. Linear encoders are used in metrology instruments and high precision machining tools ranging from digital calipers to coordinate measuring machines''

* [[data compression|Compressor]], encodes data (e.g., audio/video/images) into a smaller form (see [[codec]])

== Sensors ==

* [[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]]
