数字和表面声波(SAW)技术的新进展使它们的性能十分接近,因而目前可设计出一种信号处理模块,使之兼有数字技术的灵活性和采用表面声波技术而得到的相当快的计算速度。现已研制成每秒可处理几十兆的抽样,而其体积和功率损耗却很小的快速信号处理机。本文阐述这两种技术的兼容性和结合使用后所产生的优点,并且列举了与一维、二维付立叶以及相关处理机有关的例子。
Recent advances in digital and surface acoustic wave (SAW) technologies have made them very close in performance, so that now a signal processing module can be devised that combines the flexibility of digital technology with the relatively fast calculation of surface acoustic wave speed. Has been developed to handle tens of megabits per second sampling, and its volume and power loss is very small fast signal processor. This article explains the compatibility of these two technologies and the resulting benefits of the combination, and lists examples related to one-dimensional, two-dimensional Fourier and related processors.
