The History and Future of Fourier Analysis Workshop
(Session Code: NVCWK5)

Room Ballroom C  6:30 p.m.

Frequency analysis is often referred to as Fourier analysis but is that really true? The foundation is based on stationary and “Fourier signals.” What happens if that is not the case? Modern FFT signal analyzers use very sparse sampling that is correct according to Shannon but what will happen when using time domain analysis. Many of the myths and frequent questions will be answered using a “user perspective” and rules of thumb will be given together with good methods to avoid large errors. After attending this session, a much better understanding in regards to pitfalls and proper methodology will be the outcome.
