Course Highlights:
Why This Course Is Important
Interference in its many forms is a constant problem in electrical engineering. Interference can be related to factors such as power spikes, power grounding, use of ground planes, signal connections, radiation from digital circuits, coupling to radiated fields, susceptibility to lightning, and ESD. Circuit board design is becoming a new field of engineering with problems of crosstalk, radiation and ground bounce. With the right understanding, products and systems can be designed that will work well the first time and pass all required environmental tests. This course stresses principles not mathematics.
Who Should Attend
All engineers that are involved in product, system or facility design. This includes power engineers, digital designers, quality control engineers, product planners, computer engineers as well as engineering managers and teachers.
A review of basic electricity. Semantic difficulties. Why power grounding is necessary, soil conditions, limitations of circuit theory. Electric and magnetic fields patterns. Lenz’s law and Ampere’s law. Voltage, inductance and capacitance as field concepts. Mutual capacitance and mutual inductance. The effect of dielectrics. The concept of displacement current.
