摘要
在数字信号处理教学中采用了项目式教学法,在课堂中设定一个学生最终能够独立完成的综合性任务,通过创设情境激发学生兴趣。根据课堂内容将电子乐音合成引入课堂,结合音乐信号的特点,引入频谱分析的概念,根据计算机处理信号的特点依此引出时域离散信号傅里叶变换、离散傅里叶变换等概念,最后学生进行分组讨论、实践、答辩。使学生在学习—思考—实践的过程中完成整个教学工作。
Project-based teaching method is adopted in the teaching of digital signal processing,which sets up a comprehensive task that students can ultimately accomplish independently in the classroom,and stimulates students’interest by creating situations.According to the teaching content,electronic music synthesis is introduced into the classroom,combining with the characteristics of music signals,the concept of spectrum analysis is also introduced.According to the characteristics of computer processing signals,the concepts of time-domain discrete signal Fourier transform and discrete Fourier transform are introduced simultaneously.Finally,the students are divided into groups to discuss,practice and reply.Students are encouraged to complete the whole teaching work in the process of learning,thinking and practice.
