[SciPy-user] signal processing chapter for book

[Giorgio Luciano]

first of all sorry for cross posting
As I wrote some time ago we are trying to write a book proposal about 
the use of python/scipy/numpy in chemometrics and analytical chemistry. 
Since now I've received positive answer from eight authors and the only 
"missing" chapter is one about the use of python in digital signal 
processing (I've contacted some possible authors but since now they are 
busy).
The schedule will not too tight and the chapter doesnt' need to be too long.
Hope to hear from you soon
Giorgio
