Webbthe closed-loop nature of the PLL forces the VCO to lock in frequency with the signal input; i.e., when the PLL is in lock, the VCO frequency is identical to the signal input, except for a finite phase difference. The range of frequencies over which the PLL can maintain this locked condition is defined as the lock range of the system. Webb2 feb. 2009 · 2,099. uhf transmitter schematic.
