FOURIER SERIES RESULTS
Cosine expansion
Complex exponential expansion
Trigonometric series
Phasor for n-th harmonic
Relationship between exponential and trigonometric expansions
GENERAL STRATEGY:
. Approximate a periodic signal using a Fourier series
. Analyze the network for each harmonic using phasors or complex exponentials
. Use the superposition principle to determine the response to the periodic signal
