Research and Practice of Ideological and Political Education in “Digital Signal Processing”—Taking Measurement and Control Technology and Instrumentation as an Example

为了更好地将专业课程和课程思政相融合，提高专业课程的铸魂育人成效，本文针对《数字信号处理》课程的课程思政教学进行了积极探索。对课程思政进行了总体设计，深入挖掘了课程思政元素及融入方式。以“快速傅里叶变换(FFT算法)”知识点的教学为例进行了具体的介绍。从FFT算法的提出背景、分解思路、特点、重要性、硬件实现、应用、与人工智能前沿技术的结合七个方面，介绍了每个方面的教学案例以及融入的课程思政元素。对于《数字信号处理》课程的教学改革具有一定的参考价值，对于其它工科课程的课程思政教学也有一定的借鉴意义。In order to better integrate professional courses with ideological and political education, and improve the effectiveness of soul-building and education in professional courses, the paper explores the ideological and political education of “Digital Signal Processing” course. The overall design of the ideological and political education, the elements and the integration methods have been proposed. A specific introduction is given taking the knowledge point of “Fast Fourier Transform (FFT algorithm)” as an example. From seven aspects, including the background, decomposition ideas, characteristics, importance, hardware implementation, applications, and the integration with AI, teaching cases and the ideological and political elements integrated are produced. The paper has certain reference value for “Digital Signal Processing” course’s teaching reform and also has certain reference significance for the ideological and political teaching of other engineering courses.
