Definition

1. Noun:
   • A device for converting digital signals into analogue signals: A "digital-analog converter" is an electronic component or circuit that transforms discrete digital data (represented as binary numbers) into a continuous analogue signal (such as a varying voltage or current). This conversion is fundamental for devices that need to interpret digital information in the physical, analogue world.

Usage Examples

• Noun:
  • The sound quality from your computer depends heavily on the quality of its internal digital-analog converter.
