Colpitts Crystal Oscillator Circuit

This electronics video tutorial provides a basic introduction into the colpitts crystal oscillator circuit. The crystal oscillator for the most part determines the operating frequency of the circuit. There are two frequencies you need to be concerned about, the series resonant frequency and the parallel resonant frequency.
