Chapter 6. Case Study: Phase-Locked Loops and Differential Equation Methods

Even though it is still early in our study of simulation, we now have the tools required to use simulation effectively to investigate the design and operating characteristics of a number of important systems. While there are many candidate systems that could be explored at this point in our studies, our focus in this chapter is on the phase-locked loop (PLL). There are a variety of justifications for this choice. First, the PLL is a basic building block for many subsystems used in the implementation of modern communication systems. PLLs are widely used in frequency synthesis, for frequency multipliers and dividers, for carrier and symbol synchronization, and in the implementation ...
