ECE 4664 Analog & Digital Communications Laboratory (1C)

Laboratory experiments which deal with the design and measurement of analog and digital communication systems. Concepts include SNR, Modulation Index, PCM, and spread spectrum.

What is the reason for this course?

This laboratory is important for seniors wishing to emphasize the communications area. This course provides practical hands-on exposure to communication system building blocks, such as filters, mixers, and amplifiers, and enables students to study the effects of noise on communication systems. Communications is a highly important and growing field and students should have opportunity to gain familiarity with communication test equipment and measurement techniques

Technical Elective. Typically offered: Fall. Program Area: Communications.

Prerequisites: C- or better in 3614. Co-requisite: 4634.

Why are these prerequisites or corequisites required?

The lab is closely related to the material in ECE 4634, and builds on junior level signals and systems (ECE 3614).
