Abstract Title: W64 - Fourier and Wavelet Analysis
Abstract: In this laboratory experiment, techniques in data analysis using Fourier and wavelet analysis are introduced. First the students review Fourier series. Sound recordings of tuning forks are then made using Matlab and the students use a simple code to find the amplitudes of the frequencies present in the recording. The students then repeat the analysis using Matlab's Fast Fourier Transform utility and compare the results. Wavelets are then introduced and the recording are then analyzed using wavelet techniques to understand the similarities and differences between Fourier analysis and wavelet analysis. Finally, topics of "noise" and "filtering" are introduced and voice recordings or recordings or music are made and analyzed.
