Course Outcomes

Explain the basic causes of most electromagnetic compatibility (EMC) problems and implement design techniques that minimize those problems. 

Interpret FCC limits on radiated emissions and be able to estimate those emissions for circuit subsystems.

Calculate self and mutual capacitance and inductance for simple configurations of conductors. 

Estimate the noise coupled from one circuit to another through mutual capacitance and mutual inductance. 

Distinguish between differential-mode and common-mode currents, and be able to design devices such as common-mode chokes to suppress unwanted common mode currents. 

Explain some of the nonidealities of standard circuit components.

Predict the high frequency content of digital signals based on their rise time and other characteristics. 

Describe the differences between analog and digital circuits and the various sources of analog circuit and digital circuit noise .  

Design decoupling capacitors to reduce switching noise in digital circuits. 

Design shields for near and far sources of electric and magnetic fields. 

Determine cavity resonant frequencies and circuit board resonant frequencies and explain their potential impact on EMC applications. 

Explain the mechanisms by which materials become electrically charged, the possible effects of electrostatic discharge on electronics, and some mitigation techniques.
