| Abstract: | It has been established that the CCD implementation of a one-dimensional chirp z-transform (CZT) is fairly simple and inexpensive. The two-dimensional chirp z-transform (2-D CZT) is developed and its CCD implementation is suggested. The computational efficiency of CZT algorithm over the Fast Fourier Transform (FFT) algorithm in evaluating some Discrete Fourier Transforms (DFT) with a specified resolution is established. |
