A/D and D/A Requirements

Electrically sophisticated and high-speed processing are performed digitally in CPUs and DSPs.

Natural phenomena are converted to digital signals using an A/D converter for digital signal processing, then converted back to analog signals via a D/A converter.

Advancements in Microfabrication Technology→Signal Processing Digitization
→A/D and D/A Converters Required
