Answer 1

When converting an analog audio signal to a digital representation, an AD converter takes amplitude measurements, or samples, of the waveform at equally spaced points in time. The sampling rate — i.e., the frequency of these measurements — determines the highest frequency of the input signal that can be captured. We saw in class that an insufficiently high sampling rate causes the loss of high frequencies, resulting in muted or murky sound quality. (For a review of these ideas, see
