基于学生随身创新设备的时域信号基础实验
|
摘要
基于学生随身创新设备,软件和硬件相结合,设计与实现信号与系统课程的时域基础实验。将信号时域基础理论知识融入实验的动手实践中,在时域中观察及测试典型的信号,变简单验证性实验为复杂综合性实验,同时可克服传统实验室操作需要固定场所的缺陷,系统全面地掌握具体知识点和训练动手能力,有效提高理论教学和实验实践效果。
Based on students' portable innovative laboratory device, time-domain experiment is designed and implemented with combination of software and hardware. Integrated the fundamental theory into the hands-on practice while observing and measuring typical signals in time domain, the simple verification experiment was modified and improved to complex comprehensive experiment. The experimental results show that the proposed scheme can overcome the inconveniences caused by fixed place in the laboratory operation, guiding students to systematically and comprehensively grasp specific knowledge points and train their operational ability, effectively improve the theoretical teaching and experimental practice.
