Digital Signal Analysis

The links below take you to pages containing tutorials and applets.

• Convolution
• Discrete Convolution
• The Application of Discrete Convolution
• Correlation
• Fourier Transform
• Summary
• Fourier Series to Fourier Transform
• Discrete Fourier Transform

The tutorial documentation can also be downloaded in PDF.

Other tools relevant to EE4 (currently undocumented) are:

• Power Spectral Density
• Rotating Phasors
• Trigonometric and Complex Fourier Series
• Spectrograms
• Window Functions
• Ensemble Averaging
• Discrete Wavelet Transforms

A full download of all the tools is available as a zip file, a self extracting zip file for PCs and as a set of files for floppy disk transfer

A Note on Compatibility: Mac users should ensure that:

• If using Internet Explorer that you have the freely available Apple MRJ 2.2 Java runtime environment, and that Explorer is configured to use this to run applets.
• If using Netscape you have - in addition to the MRJ 2.2 environment above - the freely available Mozilla MRJ Plug-in installed which Netscape requires to run Java 1.1 applets.
