ANALYSIS OF THE SYNCHRONIZATION OF AN AUTOMATIC PHASE CONTROL SYSTEM,
Abstract
In this report approximation techniques are developed that predict the ranges of system parameters for which a phase-locked loop synchronizes to a sinusoidal input of constant frequency. These analytic methods are also presented as step-by-step procedures that might be useful for solving other problems of nonlinear oscillations. The differential equation is derived for the phase-locked loop with sinusoidal phase comparator. Synchronization is defined and examined for several phase-locked loops with different filters. Other factors which determine the performance of phase-locked loops are discussed. These include the pull-in time, the noise bandwidth, and the stability of synchronized loops. Finally, experimental model phase-locked loops are compared with the idealized loop. Typical values of components and measured values of performances are presented.
