WebIt turns out that the Fourier series exceeds the height of a square wave by about 9 percent. This is the so-called Gibbs phenomenon, shown in Fig. 2. Increasing the number of terms in the partial sum does not decrease the magnitude of the overshoot but moves the overshoot extremum point closer and closer to the jump discontinuity. greenpower alloa
