Harmonic Overtones and Resonance

Section 14:

Amplitude and Phase Charts for 2nd Order Low-Pass Resonance

The 1st chart on this page shows the amplitude vs. frequency response of a low-pass resonance. The 2nd chart on this page shows the phase vs. frequency response of a low-pass resonance. The 3rd chart on this page shows the phase shift of a square wave with its fundamental at the frequency of resonance.
