A/D conversion is a true/false concept: it converts continuous signals into discrete digital numbers.

• A. False
• B. True
• C. It converts digital to analogue
• D. It amplifies the signal

Answer: (B)

A/D conversion involves turning a continuous analogue signal, which changes smoothly over time, into a sequence of discrete numerical values that a digital system can store and process. This is done by sampling the signal at regular intervals and then quantizing each sample to the nearest digital value. That’s why the statement is true: analogue signals are converted into discrete digital numbers through this process. The other ideas aren’t what A/D does: converting digital back to analogue is a DAC task, and amplifying the signal is separate from the conversion itself.
