Fourier Series
The purpose of this applet is to demonstrate how different types of waveforms
can be generated by adding up weighted sinusoidal waveforms
and their harmonics.
Use the scroll bars to set the values of the sinusoidal waves and their
harmonics. It is possible to introduce a DC offset and to scale the
output waveform using the options given. The output can also be full
wave or half wave rectified if desired. To see a demonstration of some
common waveforms select one of the check boxes in the applet.
Note that all coefficient values and the DC offset have a range of -1.0 to
1.0. The scale ranges from 0 to 40.
The explanation below demonstrates how the values used in the applet
correspond to the Fourier series representation of waveforms
with coefficients in rectangular form.
