ECE 5214 Phase-Locked Loops: Theory and Practice (3C)

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.

What is the reason for 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.

Typically offered: Fall. Program Area: Electronics.

Prerequisites: 4405.

Why are these prerequisites or corequisites required?

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.
