text: # 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
