Abstract:

A Z-transform algorithm, developed for the spectral analysis of signals, allows one to get closer to the poles of a signal and effectively reduces the signals bandwidth and sharpens its peak point. It can give a high resolution, narrow-band frequency analysis with frequency spacing delta f or 1T, where T total length of the analysis interval. This algorithm also enhances the signal poles that lie on circular or spiral contours that begin at almost any point in the Z-plane and the angular spacing of points in an arbitrary constant. Since this algorithm takes advantage of high-speed convolution, it is almost as fast and more flexible than the Fast Fourier Transform FFT.
