The control of noise and electrical interference is an ongoing problem for circuits and systems designers. Without proper grounding and shielding, an electronic system’s function can be dangerously impaired by nearby communications devices, computing systems, or electrical machines. In addition, many jurisdictions are now requiring consumer and industrial electronic systems to have their tolerated level of electromagnetic interference specified and tested. After attending this course, the engineering professional will be able to address electromagnetic compatibility and grounding problems, and tune the implementation of instrumentation systems such as to improve their immunity to electromagnetic and electrostatic interference.
This session is geared towards professionals with a strong interest in grounding and shielding techniques. Group design exercises will be included.
The course will use an electronic presentation with the attendees being provided a hard copy of all slides with additional notes. Worked examples of system design for proper grounding and shielding based on industrial designs are included.
- Review the fundamentals of electrical circuits and electromagnetics;
- Study the basic theory of electrical noise and interference;
- Identify and assess the major design problems in circuit grounding and shielding;
- Learn grounding techniques in Printed Circuit Boards with analog, digital, and mixed-signal circuits;
- Learn grounding and shielding techniques for both low-frequency and high-frequency instrumentation circuits;
- Address shielding considerations when selecting cabling.
The Grounding and Shielding in Electronics Instrumentation course targets an audience of electronics, electrical, embedded systems, computer, and instrumentation and measurement engineers at bachelor's and/or master's level. The goal of this course is to provide guidance to the engineering professional who needs to address general instrumentation applications in electromagnetic noisy environments. It is assumed that the attendee has basic engineering knowledge but is not necessarily an expert in instrumentation.
