Frequency and Phase Locked Loops (PLL)

The purpose of a PLL is to generate a frequency and phase-locked output oscillation signal. To achieve this goal, prior art essentially functioned by frequently changing the PLL output frequency according to the phase error (i.e. the faster/slower phase relationship) to generate a momentary, but not static, frequency and phase locked output oscillation signal. This frequent back-and-forth change in VCO freq ...
