WebThick-Prism Chirp Filter. A thick prism is used as a chirp filter. The angle of incidence is selected to satisfy the Brewster condition in order to minimize the reflection loss. The apex angle $\alpha$ is selected such that the incident ray and the central deflected ray are symmetric with respect to the prism. Under these two conditions, show ... WebAbstract: It is shown in this paper that the discrete equivalent of a chirp filter is needed to implement the computation of the discrete Fourier transform (DFT) as a linear filtering process. We show further that the chirp filter should not be realized as a transversal filter in a wide range of cases; use instead of the conventional FFT permits the computation of …
