DSP的广度和深度

 DSP的广度和深度(中文2000字,英文1000字)
数字信号处理是二十一世塑造科学与工程技术中最强大的一项技术。它已经在:通讯、医疗成像、雷达、声纳、高保真的音乐复制、和石油勘探等广泛的领域里带来了革命性的变化。这些领域已经开发出一种以DSP技术为基础的算法、数学和专业技术。这个组合的宽度和深度使得任何个人不可能掌握所有的DSP技术开发。DSP教育包括两个任务：一是DSP的一般概念应用到学习领域；二是学习您感兴趣的特殊领域的专业技术。这一章我们将通过描述以DSP为核心的技术在几个不同的领域所带来的生动效果来开始我们认识数字信号处理器世界的旅程。
 The Breadth and Depth of DSP
Digital Signal Processing is one of the most powerful technologies that will shape scienceand engineering in the twenty-first century. Revolutionary changes have already been made in abroad range of fields: communications, medical imaging, radar & sonar, high fidelity musicreproduction, and oil prospecting, to name just a few. Each of these areas has developed a deepDSPtechnology, with its own algorithms, mathematics, and specialized techniques. Thiscombination of breath and depth makes it impossible for any one individual to master all of theDSP technology that has been developed. DSP education involves two tasks: learning generalconcepts that apply to the field as a whole, and learning specialized techniques for yourparticular area of interest. This chapter starts our journey into the world of Digital SignalProcessing by describing the dramatic effect that DSP has made in several diverse fields. Therevolution has begun.
