This directory contains applications either developed or enhanced at Washington State University. This activity is supported in part by the National Science Foundation under grant USE-9250721. All applications run succesfully under NS3.0. I have not tried to run them under 3.1 since I can not afford it. Use at your own risk. If you find them helpful or want source code, drop me a line at bamberg@eecs.wsu.edu. If you use these applications, let me know so I can keep my funding agents happy. You may need to grab gzip and gunzip from the folks at the FSF. You can find it on their ftp sight, prep.ai.mit.edu in the pub/gnu directory. Sorry for the inconvenience, but it is a real nice compressor (I get about 30% more compression than "compress"). PZ.tar.Z An application for studying various attributes of digital filters. It allows a user to interactively place and move poles and zeros of a digital filter and see how it affects the Fourier transform and impulse response. The user can select various attributes such as minimum, maximum, linear phase and see the affect on the relationships between roots, the Fourier transform and the impulse response. For real impulse response filters, code for Ein.app (developed at Princeton and available from ftp.princeton.edu) is possible to generate the digital filter and apply it to a digitized sound file. The NeXT version of Ein then generates a time-frequency analysis of the processed sound. This app is appropriate for an introductory course on DSP (senior or first year grad).
