JAVA APPLET SOFTWARE FOR ANIMATIONS AND DEMONSTRATIONS

Introduction

This page provides access to Java software developed by Dr. Dave Laurenson and Dr. Mike Jackson of the Signals and System Group of the Department of Electronics and Electrical Engineering at the University of Edinburgh. This work was funded by SHEFC. More details about the WebEng project in particular and about other related Java applets may be found here.

Feedback

If there are any problems accessing the demonstrations from this page, please contact John.Thompson@ee.ed.ac.uk. All feedback on this software should be sent to Dave.Laurenson@ee.ed.ac.uk

Contents

Seven of the demonstrations are listed below. These applets run under Java 1.1 and require no additional plug-ins to operate on PCs or Unix systems (Mac users see the note below).

The links below are organised according to the relevant parts of the book and take you to pages allowing access to the demonstrations.

• Section 1.3: Trigonometric and Complex Fourier Series
• Section 1.4: Fourier Series to Fourier Transform
• Section 1.4: Fourier Transform
• Section 1.5: Rotating Phasors
• Section 2.3: Convolution
• Section 4.4: Discrete Convolution
• Section 4.4: Discrete Convolution in Finite Impulse Response Filters
• Section 6.3.2/9.3: Window Functions
• Section 7.2: Ensemble Averages
• Section 9.3: Discrete Fourier Transform
• Section 9.5: Power Spectral Density

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.
