Harmonic Overtones and Resonance

Section 9:

Changes In Shape of Square Wave with
2nd Order High-Pass Resonance

This page features 6 charts, which show a square wave without resonance followed by charts that show the phase and amplitude changes caused by a high-pass resonance at the frequency of resonance and at 1, 2, 3, 4, and 5 octaves above the frequency of resonance.
