The inverse chirp z-transform (ICZT) can be used with chirp contours that perform partial or multiple revolutions on the unit circle, according to engineers at Iowa State University. Last year, Iowa ...

Comprehensive introduction to analysis of continuous and discrete-time signals and systems. Linear time-invariant systems, convolution; Fourier series representations of periodic signals; Continuous ...

We construct a new method for approximating Hilbert transforms and their inverse throughout the complex plane. Both problems can be formulated as Riemann—Hilbert problems via Plemelj's lemma. Using ...
