A simple teaching aid for the quantitative demonstration of Fourier analysis and synthesis is described. Any periodic waveform of the specified frequency is analysed to give its different Fourier components and these components, when added, give the synthesized waveform. The circuit arrangement is simple and inexpensive and may be assembled in any undergraduate laboratory.
