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