EE5410 Signal processing : Fourier series and complex exponentials
1. One of the primary motivation for the use of Fourier series is the fact that complex exponential signals are eigenfunctions of LTI systems.
2. We have seen that any PERIODIC signal of practical interest can be represented in a Fourier series -- ie., as a weighted sum of harmonically related complex exponentials that share a COMMON period with the signal being represented.
3. how different characteristics of signal are reflected in their Fourier series coefficients.
