Harmonic Overtones and Resonance

Section 17:

Changes In Shape of Square Wave with
4^th Order Low-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 low-pass resonance at the frequency of resonance and at 1, 2, 3, 4, and 5 octaves below the frequency of resonance.

Square wave without resonance
