Electric Behaviour of Crystals and Pierce Crystal Oscillators
The Java applet QuartzCrystal shows the frequency response of quartz crystals and Pierce crystal oscillators. Crystal parameters can be freely choosen. Display is spectrum analyzer-like and shows the amplitude/phase and/or a Nyquist diagram. Crystals can be series resonant or with load capacitance. Adding of spurious resonances is possible.
