Teaching Fourier analysis in a microcomputer based laboratory

Abstract

Using a sequence of suitably chosen signals and interesting physical examples, Fourier analysis can be taught in an microcomputer based laboratory (MBL) with a minimum of mathematics. Thus, even nontrivial applications like the response of resonance circuits to δ-function inputs can be treated on a very elementary level.

Investigating properties of white noise in the undergraduate laboratory

“…For example, this concept has already been elegantly introduced in [1]. The concept of the Fourier transform is also extensively explored in laboratory experiments in areas as diverse as optics, quantum mechanics and signal processing [1][2][3][4]. The present paper describes an experiment which simultaneously investigates various properties of electrical noise and its frequency composition.…”
