摘要

在信号分析与处理中,Z变换在离散信号系统中的作用与拉普拉斯变换在连续信号系统中的作用一样重要。分析了Z变换应用的局限性。提出了限带信号广义Z变换的新概念,得到了一些新的结果,扩展了变换理论。在实际应用中,一些传统的Z变换难以解决的问题可以通过该理论轻松解决。

Some new results on Z transform
In signal analysis and processing, the Z transform plays the same-important role in the discrete signal system as that of the Laplace transform in a continuous signal system. The limitation of the application of the Z transform is analysed. A new concept of the wide sense Z (WSZ) transform for a bandlimited signal is proposed, some new results is obtained, and the transform theory is expanded. In practical applications, some problems which are difficult to solve with the traditional Z transform can be solved easily by the proposed theory.
