Chirp z-transform--criteria for choosing parameters
I am trying to find the fourier component of a time signal, but need
a high resolution only over a narrow frequency span. I found some
information about the chirp z-transform (czt in the signal processing
toolbox) from the help menu. What are the criteria in determining
the parameters n (the no. of points from the input time signal) and m
(the no. of points chosen for the z-transform)?
Please kindly refer to any useful references on how to choose the
parameters when using the czt command.
Thanks for your help.
