【摘要】 为了在“数字信号处理”课程教学中形成对知识、能力、素质的有机融合，同时提高学生解决复杂频域问题的综合能力和高阶思维，通过以多层次案例为教学载体，以问题导向学习为教学方法，以Matlab科学软件为教学工具，构建了基于多层次问题导向学习的频域处理实验。近三年教学实践表明：学生对频域分析处理知识点的掌握程度大幅提高。更多还原

【Abstract】 In order to form an organic integration of knowledge, abilities, and qualities in the teaching of Digital Signal Processing courses, and at the same time improve students′ comprehensive ability and high-level thinking in solving complex frequency domain problems, frequency domain processing experiments based on multi-level problem-oriented learning are constructed in this paper, by using multi-level cases as the teaching carrier, using problem-oriented learning as the teaching method, and using Matlab scientific software as the teaching tool. Teaching practice in the past three years has shown that students′ mastery of frequency domain analysis and processing has been greatly improved.更多还原
