3.9 Graphics Functions 343<br />

3.9.2 FourierPlot<br />

FourierPlot[func, {t, t , t }]<br />

plots the frequency spectrum of the function func where<br />

the independent variable t is swept from t to t <br />

FourierPlot[{func <br />

, func <br />

, † † † }, {t, t , t }]<br />

superimposes the Fourier plots of several functions<br />

Command structure of FourierPlot.<br />

FourierPlot performs a discrete fourier analysis by applying Fourier on the given functions.<br />

FourierPlot inherits all options from ListPlot. Additionally the following option is available:<br />

option name<br />

default value<br />

PlotPoints 250 specifies the number of sample points<br />

Options for FourierPlot.<br />

PlotPoints<br />

The option PlotPoints −> integer specifies the number of sample points. The maximum displayed<br />

frequency is given by integert t .<br />
