Care and feeding of Discrete Fourier transforms (DTFT), especially Fast Fourier Transforms, and other operators on discrete time series. Complexity results, timings, algorithms, properties. These are useful in a vast number of applications, such as filter design, time series analysis, various nifty optimisations of other algorithms etc.

1 Chirp z-transform

Chirplets, one-sided discrete Laplace transform related to damped sinusoid representation. (; )

A recent publication () shows that these are as tractable as FFTs to invert, which is to say, very. I will read the paper and see if that is as useful to me as it seems like it might be. (The paper has a lot of elementary proofreading errors, which is a bad start.)
