现代计算机与通讯系统电子设备中广泛使用了数字信号处理专用集成电路，它们主要

用于数字信号传输中所必需的滤波、变换、加密、解密、编码、解码、纠检错、压缩、解压缩等操作。这些处理工作从本质上说都是数学运算。从原则上讲，它们完全可以用计算机或微处理器来完成。这就是为什么我们常用C、Pascal 或汇编语言来编写程序，以研究算法的合理性和有效性的道理。-Modern computer and communication systems are widely used in electronic equipment for digital signal processing application specific integrated circuit, which is mainly used for digital signal transmission required for filtering, transformation, encryption, decryption, encoding, decoding, EDAC, compression, decompression, etc. operation. The processing in essence is math. In principle, they can use the computer or microprocessor to complete. That is why we used C, Pascal, or assembly language to write programs to study the rationality and effectiveness of the algorithm logic.
