A Hybrid Analog/Digital Phase-Locked Loop for Frequency Mode
... driven exactly at resonance, since the driving force and response are no longer π/2 out of phase. Thus, while the frequency output of the PLL does change as the tip approaches the surface, the tuning fork is being driven progressively off resonance. This problem is particularly acute for high Q tran ...
