The purpose of a phase locked loop (PLL) is to generate a frequency and phase-locked output oscillation signal. To achieve this goal, prior art essentially functioned ...

The phase locked loop (PLL) is an indispensible component in modern electronic systems. Its function is to generate an accurate output signal of frequency equal to, or a multiple of, the input signal ...

Phase coherence, that is a stable phase relationship between signals, is essential when making measurements that require more than one RF output. While this was once primarily required when evaluating ...
