The Chirp Z Transform (CZT) has been applied to extract the features of HIF and/or other usual network events signal. It is possible to appropriately detect fault by low order harmonics of current signal extracted by means of CZT. Maximum discrepancy of detection is nearly 7 ms which is ...
As mentioned in numpy/numpy/issues/1177, Chirp Z-transform and special cases of it have been submitted to SciPy under public domain by Paul Kienzle and Nadav Horesh: [SciPy-user] Chirp Z transform The special cases of CZT are zoom FFT an...

The proposed method is coded in MATLAB to be performed on a single CMP Conclusions We have presented a fast algorithm for the implementation of the hyperbolic deconvolutive Radon transform (DecRT). It uses interpolation procedures to map reflection amplitudes along hyperbolic events to those along ...
In this work, Chirp Z Transform (CZT) is applied to substitute the Fast Fourier Transform (FFT) calculation in PPT, when data was sampled badly, or truncated shortly. Such a case can be seen for the well thermal conductor aluminum, whose thermal transient is quick ended, or when the data...
