The chirp z transform algorithm
網頁1982年1月1日 · (1) m=O n~O The chirp z-transform is an efficient algorithm for evaluating the z-transform of a finite duration sequence on certain general surfaces in the 2-D plane. Since a bi-circte is one of the allowable surfaces, the CZT algorithm can be used to evalu- ate the 2-D DFT of the sequence efficiently. 網頁Also, Chirp Z Transform algorithm enables sampling the z transform of a finite length sequence on a spiral contour. Combining the advantages of these transforms, the author innovated the concept of Warped, Chirp Z transform.
