Sampling for sixth formers: using a home-made spectrum analyser in A-level electronic systems

Abstract

Some years ago when the AEB A-level Electronics Systems syllabus was updated, the following work on sampling was introduced:time quantisation, sampling rate and Nyquist criterionamplitude quantisation and resolutionquantisation distortion.This seemed at first sight rather daunting. The sort of material which might appear in second year university courses on communications was to be presented to sixth formers whose maths perhaps stopped at GCSE!
