In a CD recorder, the stage that combines digital data with error control and sync word is:
Show Hint
Multiplexers combine data streams with control and sync bits to prepare data for recording or transmission.

- ADC
- Filter
- Multiplexer
- Laser unit
Show Solution
The Correct Option is C
Solution and Explanation
The multiplexer in a CD recorder integrates digital data with essential elements like error control codes and synchronization (sync) words. This process guarantees precise data retrieval and error correction during playback, packaging the raw data into a format ready for CD encoding and recording.
Additional stages handle distinct operations:
- The ADC (Analog-to-Digital Converter) digitizes analog audio signals.
- The Filter eliminates extraneous frequencies or noise.
- The Laser unit inscribes data onto the CD surface via laser beams.
