WebMay 22, 2024 · A phase-locked loop (PLL) is a feedback system in which the frequency and phase of an output signal is related to the frequency and phase of an input signal. The block diagram of a PLL is shown in Figure 6.9.1. An input signal x(t) is compared to a feedback signal z(t). The frequency of y(t) will be the average frequency of x(t). WebMoreover, a small phase theorem, as a counterpart to the well-known small gain theorem [8], for the stability of feedback interconnected LTI systems is obtained, which states that the feedback system is stable if the sum of system phases in …
