Reference implementation 'impulse invariance transform'

[Rudy Eschauzier]

Octave currently lacks a functions to perform the
transformation of a continuous time system to a
discrete time system and back, using the 'impulse
invariance transform'. The impulse invariance
transform is a key technique for digital filter and
dsp design. See also
http://www.mathworks.com/access/helpdesk/help/toolbox/signal/impinvar.html.

If anyone is interested, I have written a reference
implementation for this function that is compatible
with Octave. The implementation covers both continuous
to discrete and the reverse transform. It also handles
multiple order poles correctly (see
http://ieeexplore.ieee.org/search/srchabstract.jsp?arnumber=536691&isnumber=11401&punumber=78&k2dockey=536691@ieeejrns).

Let me know if there is any interest, and I will
gladly release under GPL.

Rudy.

Rudy,

Sorry for the delay in responding. It seems you mail got stuck in some
moderation queue somewhere.

Sure, maybe this code might be hosted on octave-forge
(http://octave.sf.net)..

Regards
David

Please add it to octave-forge octave-dev@....

Either send us your sourceforge ID and we can add you
to the project, or send the function and we can add
it ourselves.
