摘要
信号处理是关于信号观察、测量和变换信号的技术。它的基本组态是通过时间、空间或者频率在不同坐标轴上进行变换,以便更容易地掌握其特征与性质。当今的数字化时代,许多模拟信号都转为数字信号进行处理。电子系统是由若干相互联接、相互作用的基本电路组成的具有特定功能的电路整体。在电子系统中信号处理理论得到了广泛的应用。本文还简要地介绍了数字信号处理器DSP在一些电路中的应用。
The signal processing is a technique concerning the signal＇s observation, measurement and the transformation. The base states is to control its characteristics and properties more easily by finish the transformation of time, space or frequency on the different stalk .In this digital ages, many analogy signals are turn into the digital signal to carry on the processing. The electronics system is a aggregate with special function which is made of many basic electric circuits interacting each other reciprocally . The signal processing theory gets the extensive application in the electronics system. Except above, the other applications of digital signal processor other applications in the electric circuits are introduced to in this paper.
