中文摘要: |
学生普遍反映数字信号处理课程公式繁多,所开设实验脱离工程实践。针对此问题,设计了“数字工频陷波器”实验。基于学生已学课程,综合运用Multisim、MATLAB等软件工具作辅助开发,使用运算放大器、单片机等器件完成本实验。实验方案具有多样性,针对不同的学生,实验参数容易调整。实践表明,本实验可使学生提高对本课程的兴趣,加深对理论知识的理解程度,提高学生对知识的综合运用能力和动手能力。 |
英文摘要: |
Most students think that the formula in the digital signal processing course is numerous and is difficulty to understand. And the experiments in the course are out of engineering practice. To resolve this problem, we design the digital power frequency notching filter experiment. Based on the courses that have studied the students must comprehensive use Multisim/MATLAB software, and use OP amplifier and MCU to accomplish this experiment. There isn’t only one method to achieve this experiment, to any student the experiment parameter can be adjustable. Practice shows that this experiment can improve the students’ interest of the course, can deepen the students’ understanding of the theoretical knowledge, can improve the students’ ability to analyze and solve problems. |
