A digital audio recorder uses an analogue-to-digital converter (ADC) to convert sound waves into a format that can be stored on a computer.

The diagram below represents the process of digitising an analogue sound wave.

An analogue sound wave curve plotted on a graph. The vertical axis is labelled P. The horizontal axis is labelled Q. Vertical dashed lines are spaced at equal distances along the horizontal axis, meeting the wave curve. The horizontal distance between consecutive vertical dashed lines is labelled R.

Identify the correct terms to replace the placeholders P, Q, and R in the diagram to show how analogue sound is sampled.
