蔡坤宝博士,重庆大学通信工程学院教授,信号与信息处理硕士学位点负贵人。长期从事信号与信息处理的教学与科研工作。近十余年来,积极探索和实施中英文双语教学,现任重庆大学大类系列课程“信号与系统”建设项目负责人,重庆市精品课程“信号与线性系统”负责人、双语教学示范课程“信号与系统”负责人,并承担重庆市精品课程“数字信号处理”的建设工作。
总体而言,如果将市面上众多的DSP教材比作不同风味的菜肴,那么这本《数字信号处理(第2版)(英文版)》无疑是一道经过精心烹饪、营养均衡的“硬菜”。它在理论的深度挖掘上毫不含糊,确保读者能够扎实掌握数字信号处理的数学基础和核心原理;同时,它在教学方法的编排上又显得极为老道,通过清晰的逻辑链条和丰富的例证,将原本可能晦涩难懂的内容变得层次分明、易于吸收。对于希望系统学习、并能将知识应用于复杂工程问题的读者来说,这本书的价值是毋庸置疑的。它不仅是一本参考书,更像是一个耐心的导师,引导你一步步跨越从理论到工程实践的鸿沟。我个人认为,这本书的价值足以支撑它成为任何DSP课程的指定教材,或者作为专业人士案头必备的工具书。
评分与其他一些教材相比,这套书在“可读性”方面确实下了一番功夫,尽管它是英文原版,但作者的行文风格非常清晰且富有逻辑性。阅读过程中,我感觉自己像是在与一位经验丰富的教授进行一对一的交流。比如在讨论窗函数设计时,作者没有简单地罗列各种窗函数的特性,而是通过对比理想低通滤波器和实际滤波器之间的误差来源,自然而然地引出了截断效应和窗函数的作用,这种“问题导向”的教学方式,让我对设计的初衷理解得更为透彻。再者,书中对于某些关键概念的“小贴士”或“注意事项”部分,往往能点出那些容易让人混淆的陷阱,比如在进行有限脉冲响应(FIR)和无限脉冲响应(IIR)滤波器的选择与对比时,作者的比较分析就做到了极其到位,明确指出了各自的优缺点和适用场景,避免了知识点上的“一锅烩”。对于自学者而言,这种细致入微的引导是至关重要的,它能有效降低理解的门槛。
评分翻阅这本教材的过程中,我发现它在深度和广度上都做得相当出色,绝非那种只停留在表面概念介绍的入门读物。尤其是在高阶主题的处理上,比如多速率信号处理和自适应滤波器的章节,作者的阐述深入到了算法的核心,并且不回避那些理论上较为尖锐和困难的部分。我记得在学习最小均方(LMS)算法时,书中不仅给出了收敛性的证明思路,还详细对比了不同步长选择对算法性能(如收敛速度和稳态误差)的影响,这种对细节的把握,让我在后续做课程设计时能够更有信心地选择合适的工具。此外,书中大量的习题设计也极具挑战性,它们不仅仅是公式的简单代换,很多都需要综合运用前面学到的多个知识点进行分析和推导,这极大地锻炼了我的独立解决问题的能力。对于那些希望未来从事DSP算法研发或更深层次研究的读者来说,这本书无疑是一份极其宝贵的资源,它所提供的知识深度已经超越了普通本科课程的要求,更接近于研究生教材的水准。
评分这本书的另一个突出优点,是其对理论与实践结合的重视程度。虽然是理论教材,但作者并没有完全脱离工程实际。在讲解数字滤波器设计时,从最基础的频域指标要求出发,逐步过渡到时域的系数确定,再到利用Matlab或类似工具进行仿真验证的流程,讲解得环环相扣。我特别欣赏它在介绍某些高级算法时,会适当地引入一些硬件实现的考虑因素,比如计算复杂度、量化误差对系统性能的影响。虽然它没有提供详细的Verilog或VHDL代码,但这种对工程约束的提前预警,让我能够从一开始就建立起“理论设计”和“实际落地”之间的联系。这对于我们这些即将步入工程界的学生来说,是弥足珍贵的。掌握的知识不再是孤立的数学公式,而是可以转化为实际产品和系统的设计蓝图,这极大地提升了学习的实用价值和成就感。
评分这本《数字信号处理(第2版)(英文版)》的教材,初拿到手时,我最直观的感受就是它的“厚重感”。从排版到内容深度,都透着一股严谨的学术气息。作为一名在校的电子信息工程专业学生,我深知DSP是理解现代通信、图像处理乃至人工智能底层逻辑的关键。这本书的结构安排非常合理,它没有一上来就抛出那些令人望而生畏的复杂公式,而是先用非常直观的例子和清晰的数学背景知识铺垫,比如对傅里叶分析的复习和离散时间系统的基本概念,这对于我这种基础不太扎实的读者来说,是极大的福音。尤其让我印象深刻的是,它在讲解Z变换和离散时间傅里叶变换(DTFT)时,插图和推导步骤都做得极其详尽,即便是初次接触这些概念,也能顺着作者的思路一步步理解其物理意义,而不是仅仅停留在符号操作的层面。教材中大量的实例,无论是滤波器设计还是谱分析,都紧密结合了实际应用场景,这使得抽象的理论知识变得“有血有肉”,极大地激发了我深入学习的兴趣。可以说,这本书为我打下了一个非常坚实的理论基础,是教科书中的典范之作。
