An important area in the field of electrical engineering is the study of phase lock loops, which are used in many applications such as frequency demodulation. Generally, the study of phase lock loops focuses on their implementation in communication systems using an LM565 chip or equivalent. However, phase lock loops can also be analyzed as a control systems problem. This paper presents the theory and analysis of phase lock loops and provides a description for showing how the frequency signal can lock into the reference signal. Simulation and experimental results validate the theoretical development, which allows for other instructors of control systems courses to incorporate a laboratory experiment in phase lock loops.
