It then performs the Fourier transform of ... absolute value of the sinc function, since the scope shows the ?>magnitude?> spectrum. The chapter finally reviews generation of a periodic signal that ...

Import RF waveform from text file exported from Siemens IDEA simulator sinc_waveform = extract_rf_pulse('sinc_pulse.txt', 0) # Convert the numpy array into an RF pulse object for pulse amplitude ...

A python implementation of the fast sinc-transform described by Greengard et. al., 2006 as implemented by Hannah Lawrence in fast-sinc-transform. Utilizes FINUFFT and fastgl (modified to use numba).

Fourier Transform: A mathematical operation that transforms a function of time (or space) into a function of frequency, allowing for analysis in the frequency domain. Sinc Function: A mathematical ...

a novel method for enhancing echo detection in the bionic-pulse fractional Fourier transform (FrFT) domain is proposed to reduce reverberation interference when detecting undersea targets. First, the ...

the matched filter still has the effect of pulse pressure [8]. Typical time-frequency analysis methods of short-time Fourier transform, Wigner-Ville distribution and improved wavelet transform ...
