PLL principles system and its applications in. harmonic analysis are firstly discussed and then integrated. presenting methods to increase the PLL-based instrumentation. efficiency. A comparison between the performance of systems. before and after the application of these methods are shown to. validate the efficiency o f the proposed methods.
