Fourier Series Applet, Square to Triangle

Cuthbert Nyack
The diagram below shows the signal examined here. As "a" changes from 0 to 0.25 the signal changes from a square wave to a triangle wave.
The applet below shows the spectrum and reconstruction of a Square wave with slope.

parameter a can be changed by scrollbar 2.
ns changes the number of terms summed.
t shows the error at any time within a period.
eok, mk changes the gain of the even/odd, magnitude spectrum.
ek changes the gain of the error.
