PLL Performance in the Presence of Noise
PLL Performance in the Presence of NoiseNoise is an extremely important issue in the wide field of PLL applications. Noise has two entirely different aspects, however. In a first category of applications, the PLL is used to extract weak signals from an extremely noisy environment. The PLL has been very effective in space communications where it is used to detect signals buriNed in noise. In this situation, the input signal of the PLL is a low bandwidth signal with large superimposed broadband noise. In a quite different category of applications—for instance, frequency synthesizers—the PLL is required to generate an output signal with high spectral purity. Here, the PLL does not “receive” a noisy input …
