数字技术和声表面波技术的最新进展已使它们相互兼容,并且现在有可能设计出这样的信号处理组件,即它兼有数字技术的灵活性和声表面波技术的极高计算速度。现在已能制造极快速的信号处理机,它每秒能处理数千万采样,而其体积和功耗却有限。本文指出这两种技术的兼容性和将它们结合使用得到的好处。本文介绍了几个关于一维和二维付里叶和相关处理机的例子。
Recent advances in digital technology and surface acoustic wave technology have made them compatible with each other and it is now possible to design signal processing components that combine the flexibility of digital technology with the high computational speed of surface acoustic wave technology. It is now possible to create a very fast signal processor capable of processing tens of millions of samples per second with limited volume and power consumption. This article points out the benefits of both technologies and their use in combination. This article describes several examples of one-dimensional and two-dimensional Fourier and related processors.
