数字信号处理的原理，PPT格式

过去，信号处理一直采用模拟设备来

完成。近代，数字计算机的出现和大规模

集成技术的高速发展，为信号处理提供了

强有力的手段。在电子技术各个领域，例

如雷达、声纳、语言通信、数字通讯等，

正日益广泛的用数字方法替代模拟方法实

现信号处理。因此,从本世纪60年代以来，

逐步形成了一门新的学科——数字信号处

理。

-Digital Signal Processing Principle, PPT format of the past, has been using analog signal processing equipment to complete. In modern times, the emergence of digital computers and large-scale integration technology of rapid development, for the signal processing provides a powerful tool. Electronic technology in various fields, such as radar, sonar, speech communications, digital communications and so on, are becoming increasingly wide range of alternative methods of analog with digital signal processing method. Therefore, since the 60s of this century, and gradually formed a new discipline- Digital Signal Processing.
