DiscreteChirpZTransform
DiscreteChirpZTransform[list]
gives the chirp Z transform of list.
DiscreteChirpZTransform[list, n]
returns a length n chirp Z transform.
DiscreteChirpZTransform[list, n, w]
uses a spiral path on the complex 
plane defined by w.
DiscreteChirpZTransform[list, n, w, a]
uses a as the complex starting point.
DiscreteChirpZTransform[list, {n1, n2, ...}, {w1, w2, ...}, {a1, a2, ...}]
gives the multidimensional chirp Z transform.
Details
- The chirp Z transform is an algorithm for evaluating the list Z transform of a finite duration sequence along a spiral path in the
plane of the form 
. With DiscreteChirpZTransform[list, n, w, a], the Z transform is evaluated at points 
for integers 
from 0 to 
. - DiscreteChirpZTransform[list] is equivalent to DiscreteChirpZTransform[list, Length[list]].
- DiscreteChirpZTransform[list, n] is equivalent to DiscreteChirpZTransform[list, n, Exp[2
/n], 1]. - DiscreteChirpZTransform[list] is equivalent to Fourier[list, FourierParameters->{1, -1}]. »
