Course Information

Description

Fundamental theory and design concepts of frequency synchronization techniques. Emphasis is on phase-locked loops and applications in communications for frequency synthesis, tracking, and demodulation. Laboratory investigates fundamental principles of operation with a final project to devleop specific aspects of a loop in detail.

Why take this course?

This course provides a broad coverage of phase-locked loops (PLL) as used in a variety of industrial and communications environments. It is the basis of the graduate work in communication circuits along with the course ECPE 5224. It is unique in the laboratory work, which provides a student with a full understanding of the problems of implementing a PLL for frequency synthesis, tracking, or demodulation.

Prerequisites

4405

ECPE 4405 is a required undergraduate course, which introduces the concepts of feedback and stability. Such tools, as root-locus and Bode plots are desirable.

Major Measurable Learning Objectives

  • Design a phase-locked loop for application as a frequency synthesizer, frequency tracking filter, and demodulator for AM, FM, and FSK signals.
  • Understand the principles of operation, the nonlinear solution technique for acquisition analysis, and the effects of the loop components on the system performance
  • Design and construct a basic PLL and predict its performance.
