DSP: Inverse chirp z-transform, where it works and doesn’t work

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 State engineers Alexander Stoytchev and Vladimir Sukhoy created a closed-form solution for the ICZT, which generalises the inverse fast Fourier transform (IFFT) off the ...
