ECE 5234 EMI and Noise Reduction Techniques (3C)

Theory and practice of E.M. noise coupling; Techniques for noise reduction: shielding, grounding and filtering. Measurement of EMI to comply with government regulation. EMI problems and solutions to switching power supply applications. Design of EMI filter.

What is the reason for this course?

Electromagnetic interference requirements, and means for meeting these requirements, has become a critical aspect of circuit design. This material is essential for students intending to specialize in practical circuit design. It is, however, of a more specialized and advanced nature than is practical to include in an undergraduate curriculum.

Typically offered: Spring. Program Area: Electronics.

Prerequisites: Prerequisites: 4224 or 4205.

Why are these prerequisites or corequisites required?

Understanding the design of amplifier circuits (as covered in 4205) or switching power circuits (as covered in 4224) is necessary to understand noise problems and noise abatement techniques applicable to these circuits.

Department Syllabus Information:

Major Measurable Learning Objectives:
    the student will have both the theoretical background and practical skills to quantify the noise and interference problems in many electronic systems, and to devise means to reduce this noise.
