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)
