Which is an example of A/D conversion?

• A. Sound sampling for computer storage
• B. Converting digital signals to analogue
• C. Filtering noise
• D. Amplifying signal

Answer: (A)

A/D conversion means turning a continuous (analog) signal into digital data that a computer can store and process. Sound sampling for computer storage is a perfect example because it measures the sound’s amplitude at regular intervals and converts each measurement into a numeric value. Those numeric samples form the digital representation of the sound. The other options describe different actions: converting digital signals back into analogue is the opposite process (D/A conversion), filtering noise is about removing unwanted components but doesn’t by itself convert the signal’s form, and amplifying the signal increases its strength without changing its format from analog to digital.
