Fourier Series Applet, Frequency Shift

Cuthbert Nyack

In addition to shifting the signal f(t) in time, the spectrum can also be shifted. The diagram below shows the 1 sided spectrum after being shifted.

The applets show the effect of shifting the one sided (a_n, 1 < n < ¥). Frequency shift is given in terms of the fundamental frequency. The horizontal axis corresponds to T, the period of the original square wave. When the single sided spectrum is shifted, the result is the wave(red) as shown below. The spectrum is shown in green.

When activated the following gif image show how the applet should appear.
