The Chirp Z-transform (CZT) is a generalization of the Z-transform that is particularly useful for evaluating the Z-transform on a spiral contour in the complex plane. It can be especially advantageous for computations involving systems with non-uniformly spaced frequency components or for analyzing signals with specific frequency characteristics.
