针对传统信号分析与处理实验以验证性实验为主,综合性实验不易开展的缺陷,提出基于myDAQ的心电信号分析与处理综合实验设计方案。学生设计部分实验电路,心电信号经实验电路调理后通过myDAQ进入计算机,由后续软件进一步处理。整个实验可在实验室以外的场所进行。实践证明,本方法更加灵活高效,在加深学生对理论理解的基础上,加强了学生的工程实践能力与创新能力的培养。 Aiming at the defects of traditional signal analysis and processing experiments, which are mainly based on confirmatory experiments and difficult to be carried out in comprehensive experiments, a comprehensive experimental design scheme of ECG analysis and processing based on myDAQ is proposed. Student design part of the experimental circuit, ECG signals through the experimental circuit conditioning through myDAQ into the computer, further software by the follow-up. The entire experiment can be carried out outside the laboratory. Practice has proved that this method is more flexible and efficient. On the basis of deepening students ’understanding of the theory, students’ engineering practice ability and innovation ability are strengthened.
