Abstract Title: W33 - Fourier Methods
Abstract: Although oscilloscopes are most often used to observe electrical signals as a function of time, seeing the same signals as a function of the frequencies of which they are composed, the frequency domain, provides powerful, and often unexpected, insights. TeachSpin's Fourier Methods is a complete experimental 'arena', built around the SRS-770 Waveform Analyzer, specifically designed to teach physics students how much can be learned about physical systems by understanding the frequency content of the signals emerging from them.  No matter what your acquaintance with the Fourier spectrum, you'll find something new to do with our electrical/mechanical/acoustical package of experiments.

Participants will:
• See how the Analyzer responds to simple waveforms
• See the operation of summing, and of multiplying, in time and frequency domains
• Choose parameters of AM or FM waveforms, and see their frequency spectra
• See the spectra of chaotic waveforms
• Tune a mechanical 2-mode resonator, seeing its spectrum reveal its normal modes
