Lets get a decent FAQ together. Now. My contributions below. Any volunteers
to maintain it?

0. What is comp.dsp?
   comp.dsp is a worldwide UseNet news group that is used to discuss 
  various aspects of digital signal processing. It is unmoderated, though
  we try to keep the signal to noise ratio up. (DSP joke that :-)
  If you need to ask a question that isn't in the FAQ, and can't figure
  out how to post, consult news.newusers.questions.
   Other relevant news groups are comp.compression, sci.image.processing.

3. Summary of DSP books and significant research articles.

(1) Major windowing articles.
>From: evans@eedsp.gatech.edu (Brian Evans)
Perhaps the classic overview paper for discrete-time windows is

@inproceedings{
   harris:windows,
   title   = "On the Use of Windows for Harmonic Analysis with the DFT",
   author  = "F. J. Harris",
   booktitle = ieeeproc,
   year    = 1978,
   pages   = "51--83",
   month   = jan
}
It discusses some 15 different classes of windows including their
          spectral responses and the reasons for their development.

  Some other articles, while sligthly narrower of scope, include:

  "Some Novel Windows and a Concise Tutorial Comparison of Window
  Families", Nezih C. Geckinli & Davras Yavuz, IEEE Transactions on
  Acoustics, Speech, and Signal Processing, Vol. ASSP-26, No. 6,
  December 1978.

  "Some Windows with Very Good Sidelobe Behavior", Albert H.
  Nuttall, IEEE ASSP, Vol ASSP-29, No. 1, February 1981.

  "Optimum Low-Order Windows for Discrete Fourier Transform
  Systems", Hrvoje Babic & Gabor C. Temes, IEEE ASSP, Vol. ASSP-24,
  No. 6, December 1976.

4. Where can I get some free/cheap software for dsp?

>From: evans@eedsp.gatech.edu (Brian Evans) - with corrections by 
hards4@ee.adfa.oz.au

 There was an entire session on this subject at ICASSP '92
	chaired by Dr. Sally Wood and Dr. James McClellan.  It appears
	in Volume 4 of the Proceedings pages 73-112.

	Sample of educational software in the public domain:

        (1) Ptolemy--- block diagram simulator for DSP systems.
            Runs on Suns under X. Graphical interface. See ICASSP '92 session.
            Contact:  Joe Buck at UC Berkeley  jbuck@janus.berkeley.edu

        (2) Khoros--- block diagram simulator for image processing.
            Runs on Suns under X.  Graphical interface.  1-D SP supported.
	    There is an entire Usenet news group for Khoros - comp.soft-sys.khoros
	    Contact:  Univ. of New Mexico

        (3) DSP Tutorials---  computer-aided instruction
	    Runs on Suns under SunView. Graphical interface.
	    See ICASSP '92 session.
	    Contact:  Dr. Sally Wood  

	Sample of public domain extensions to existing software:

        (1) Mathematica--- Signal Processing Packages (SPP) and Notebooks
            SPP implements 1-D symbolic convolution and 1-D/m-D linear
	    transforms (showing intermediate results).  Tutorial Notebooks
	    written on analog filter design, DTFT, convolution, z-transform.
	    SPP-- Contact:   Brian Evans at evans@eedsp.gatech.edu
	          FTP site:  gauss.eedsp.gatech.edu (different archive formats)

        (2) Mathematica--- Controls Systems Packages (COSYPAK) and Notebooks
	    follows the textbook "Modern Controls Theory" by Ogata.
	    The packages are largely based on SPP (above).
	    COSYPAK Contact:  Dr. Sreenath at sree@veda.esys.cwru.edu 
		    FTP site: veda.esys.cwru.edu

        (3) Maple--- Linear systems toolbox
	    Contact:  Tony Richardson  amr@egr.duke.edu
	    FTP site:  cameron.egr.duke.edu  (pub/maple/linsys.tar.Z)

        (4) Malab--  A plethora of toolboxes are available via FTP
	    FTP site:  research.att.com  (use netlib for the username)

        There are many course sequences being developed based on commerical
	programs.  In this case, the extensions to the commerical programs
	would come with the purchase of the textbooks, e.g.

        (1) Matlab--- four-part DSP curriculum, including Stochastic SP
	    Authored by Drs. McClellan, Parks, Burrus, and Schussler.
	    See ICASSP '92 special session.

Gabriel is a hierarchical block diagram programming system for prototyping
signal processing systems on single or multiple processors.  It has an
optional graphical interface.  Its current capabilities include:


HOW TO GET IT:
Anonymous ftp to copernicus.berkeley.edu, and retrieve
gabriel-license.shar.  This is a shar file of licenses that you must sign
and mail back to us (the old-fashioned way) before we can give you the
source.  Then we can tell you the password for an account that will allow
you to FTP Gabriel.

5. Where can I get the motorola DSP C compilers source?
    There are two separate compiler sources. One is the port of gcc done
    by a private induvidual (who - much more data required!) and the other
    is a port of gcc done by Motorola and returned to the FSF. These are
    both currently for gcc 1.40, but should be portable to gcc2.x.x.
    Neither of these compilers includes an assembler. {Need ftp sites..}

6. Where can I get a free compiler for the C30/C40 ?

   Currently, you can't. {any corrections to this - anyone working on it?}

7. OK then, where can I pay money for a C30/C40 compiler ?
   
   TI has a C30/C40 compiler for C. Tartan has an ADA compiler. Computer
   Motion has a C++ compiler for C3x based on GNU C++, but it appears they 
   haven't returned the deltas to FSF.

8. Where can I get some algorithms?
   This is sourced from phillip@ee.adfa.oz.au (Phillip Musumeci) and the 
   netlib help file.
    (1) there is host ux1.cso.uiuc.edu  - log in as anonymous, cd math

    (2) there is the netlib host which also serves some of this software via
     email. Try mail to netlib@ORNL.GOV with "send help" in the subject
     field.
     For Europe: 
        Internet:       netlib@nac.no
        EARN/BITNET:    netlib%nac.no@norunix.bitnet
        X.400:          s=netlib; o=nac; c=no;
        EUNET/uucp:     nac!netlib
     For the Pacific, try    
           netlib@draci.cs.uow.edu.au
     For background about netlib, see Jack J. Dongarra and Eric Grosse,
     Distribution of Mathematical Software Via Electronic Mail, Comm.
     ACM (1987) 30,403--407.
     
     A similar collection of statistical software is available from
           statlib@temper.stat.cmu.edu.

     The symbolic algebra system REDUCE is supported by
          reduce-netlib@rand.org.

    (3) It may be possible to get a set of fortran routines from the
    Naval Surface Warfare Centre. { Any one got more data ?}

    (?) if you don't know where to find what you're after, try archie.
