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.
