Osc Week 4

Oscillator Xtal Colpitts

This week we wrap up LC oscillators and Pierce Xtal oscillator.  We have a look at Varicaps in circuits and see how we can electronically adjust frequency, especially with digital memory and selecting different voltages for varicaps in different ranges to give a wide range of variable capacitance. So at this point we have studied the Pierce, Hartley, Colpitts, Armstrong oscillators.
