| Keywords: Harmonic oscillator gain.png Log-log plot of the frequency response of an ideal harmonic oscillator made with Gnuplot The three sections of the graph can be understood as follows Below resonance the gain is approximately one because the oscillator simply follows the driving force neither amplifying nor attenuating it Near resonance the energy builds up inside the oscillator and the gain reaches a maximum in a real oscillator the height and sharpness of the peak are limited by the Q factor At higher frequencies the oscillator cannot keep up with the rapidly varying driving force so the signal is attenuated more and more and also shifted 180 degrees out of phase Own 2007-06-19 Keenan Pepper Harmonic oscillators | ||||
