# Encoder

Encoder may refer to:

## Electronic circuits

* 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 encoder, creates DC balance on a communication transmission line

## Media compression

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

## Sensors

* 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
