7. The frequency drift is defined as the change in oscillator frequency when the ambient temperature varies from
8. Switch-on drift is defined as the change in oscillator frequency between 5 s and 15 mins after switch on.
9. With thermal compensation, the capacitors of the tank circuits have the following temperature coefficients:
