This talk also involved some Mathematica demonstrations. The worksheets are
available for download below.
- ECGdemo.nb: This approximates a set of electrocardiogram
(ECG) data by taking the discrete Fourier transform and constructing a truncated
Fourier series. Requires the data set ECGdata.csv and the
figure ECGchart.png.
Note: The ECG data is taken from the MIT-BIH Arrhythmia Database (PhysioNet.org).- Moody GB, Mark RG. The impact of the MIT-BIH Arrhythmia Database. IEEE Eng in Med and Biol 20(3):45-50 (May-June 2001). (PMID: 11446209)
- Goldberger AL, Amaral LAN, Glass L, Hausdorff JM, Ivanov PCh, Mark RG, Mietus JE, Moody GB, Peng C-K, Stanley HE. PhysioBank, PhysioToolkit, and PhysioNet: Components of a New Research Resource for Complex Physiologic Signals. Circulation 101(23):e215-e220 [Circulation Electronic Pages; http://circ.ahajournals.org/cgi/content/full/101/23/e215]; 2000 (June 13).
- ImageProcDemo.nb: This file shows you how to take the Fourier transform of an image, and distort the image by modifying the frequency data. The original uses the photo Mona.jpg, but you can easily replace this with a photo of your choosing.
