Coursera 课程《数字信号处理入门》旨在为学员提供数字信号处理（DSP）的基本概念和实际应用。课程的重点在于理解DSP的实际用途，而非深入探究其理论和数学细节。 课程内容包括： * **DSP的实际应用**: 通过一系列Python程序演示DSP在实际生活中的应用，例如： * 去除音频文件中的噪声 * 去除图像中的噪声 * 识别按键电话的按键音 * 分析温度数据 * **Python编程基础**: 为没有Python编程经验的学员提供Python的入门介绍，以便他们能够理解和运行课程中的程序。 * **数学概念回顾**: 课程会回顾必要的数学概念，特别是与DSP相关的复数和复指数，并通过提供练习题和详细解答来帮助学员掌握。 * **循序渐进的学习**: 课程设计注重实用性，力求让学员不仅理解概念，还能看到如何在实际问题中应用所学知识，避免了过于理论化和数学化的内容。 这门课程适合想要了解DSP的实际应用和基本原理，但不侧重于深奥理论和复杂数学的学习者。
When I was an undergraduate I took a course called Linear Systems, which provides background theory for courses like Digital Signal Processing, Control Systems, and Communication Systems. While I did earn a grade of A in the course, I never really understood the purpose of the course beyond it being a prerequisite to other courses that I was required to take. My goal in this course is to introduce you to digital signal processing in such a way that you not only understand the purpose of the various topics, but that you also see how you can apply the material. In order to demonstrate practical applications of digital signal processing, I provide about a dozen Python programs for doing such things as removing noise from audio files, removing noise from images, identifying which phone numbers are pressed on a touch-tone phone, and analyzing temperature data. I go over each program, explaining how it works and how I designed it. I don't assume that you have already programmed using the Python programming language, so I also provide a crash course to get you up to speed. This course is not for someone wanting a rigorous, theory- and math-heavy course; there are many available options if this is what you are looking for. This isn't to say that we will not use math in this course. I think that there is too much that you need to know that you can't really understand without some math. To help you with the math that we will learn, I review complex numbers and complex exponentials at the beginning of the course. Then as we learn new topics I provide practice problems with my solved answers.
