A marine research hydrophone captures underwater acoustic pressure waves as continuous analogue signals. To store and process this acoustic data on a digital computer, the analogue signal must be sampled and converted into binary.
The diagram below represents this sampling process.

Identify the correct technical terms that should replace the labels [X], [Y], and [Z] to complete the diagram.
Data representation Questions
Practise Edexcel GCSE Computer Science Data representation with exam-style questions for GCSE Computer Science. 50 questions covering Encoding characters with 7-bit ASCII, Representing bitmap images in binary, Representing analogue sound in binary, and Limitations of binary representation, matched to the Edexcel GCSE Computer Science (1CP2) specification and written in Paper 1 and Paper 2 style. Every question includes a full worked solution and mark scheme, so you can see where marks are awarded rather than just whether you got the answer right.
