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
