What is sampling resolution?

• A. The precision of each sample
• B. The rate at which samples are taken per second
• C. The total duration of recording
• D. The number of samples overall

Answer: (A)

Sampling resolution is about how finely each sample represents the signal. It refers to the precision of the amplitude value captured at every sampling moment, determined by the number of bits used per sample. More bits mean more possible amplitude levels, which lets the digital value better match the original analog signal and reduces quantization error. The idea here is the detail in each sample, not how often samples are taken, how long the recording lasts, or how many samples there are in total. Those other aspects describe sampling rate, duration, and total sample count, which are about timing and length rather than per-sample detail.
