数字信号处理(Digital Signal Processing，简称DSP)是一门涉及许多学科而又广泛应用于许多领域的新兴学科。20世纪60年代以来，随着计算机和信息技术的飞速发展，数字信号处理技术应运而生并得到迅速的发展。数字信号处理是一种通过使用数学技巧执行转换或提取信息，来处理现实信号的方法，这些信号由数字序列表示。在过去的二十多年时间里，数字信号处理已经在通信等领域得到极为广泛的应用。德州仪器、Freescale等半导体厂商在这一领域拥有很强的实力。

-Digital signal processing (Digital Signal Processing or DSP) is an emerging discipline involves many disciplines and is widely used in many areas. Since the 1960s, with the rapid development of computer and information technology, digital signal processing technology came into being and rapid development. Digital signal processing is performed through the use of mathematical techniques convert or extract information, to deal with the real signal, these signals are expressed by the sequence of numbers. Extremely wide range of applications in the past 20 years, digital signal processing in communications and other fields. Texas Instruments, Freescale Semiconductor manufacturers in this area has a strong strength.
