For this reason, quartz crystal oscillator circuits tend to be more exceptional in comparison with other resonators like LC circuits, tuning forks. Commonly in Microprocessors and Micro controllers we've been using an 8MHz crystal oscillator. A crystal oscillator is really an Digital circuit that makes use of the mechanical resonance https://crystal-oscillator26937.theideasblog.com/35408752/crystal-oscillator-for-dummies
