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

An '''encoder''' is a [[device]] used to [[encode]] a [[bitstream]] or other [[signal]] or [[data]] into a form that is acceptable for [[transmission (telecommunications)|transmission]] or [[storage]]. This is usually done by means of an [[algorithm]], especially if any part is [[digital]], while most [[analog]]ue is done with [[circuit]]ry.

==Electronic circuits==

''See also [[endec]].''

* [[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==

----

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

== Sensors ==

An '''encoder''' is also a sensor or transducer for converting rotary motion or position to a series of electronic pulses.

* [[Encoder (position)]]

--''from the [[Free On-line Dictionary of Computing]]''

** [[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]]
