Is the resonator a frequency sensitive device or is it a signal source?I believe its the former but why does a transistor needs resonator to operate as an oscillator(A resonator is just selecting a frequency,its not producing oscillation by itself)?A parallel oscillator just has the highest impedance at its resonant frequency.How can it make the transistor oscillate at the same frequency (where is the signal coming from in an otherwise "DC" circuit)?
