- 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).
