Compare analogue and digital sounds. Give an example of each.

Answer 1

Analogue sounds are continuous waves that vary in frequency and amplitude, while digital sounds are represented by discrete values or data points.

An example of analogue sound is a vinyl record playing music. The sound is produced by a needle tracking along the grooves on the record, which creates continuous sound waves.

An example of digital sound is an mp3 file playing music on a computer or smartphone. The sound is represented by a series of binary values, which are converted into audio signals by a digital-to-analog converter.
