Teaching Design of the Frequency Domain Analysis Method for the Course of Signals and Systems Based on the Integrated Classroom Practice
摘要
Abstract
The course of Signals and Systems plays a crucial role in the knowledge system of electronic information majors as a fundamental course.An integrated classroom pratical teaching of"frequency domain analysis method"is designed,which is an important method in the cource,and a visual teaching approach based on a unificed system platform for three domain analysis problems is proposed,including the response of linear and time invariant system to the deterministic signal,Nyquist sampling theorem and signal reconstruction based on sampled signal.Through independent practice,students can visualize and perceive theoretical knowledge,and in this process,they can realize reverse reasoning verification and achieve the goal of self-perception.Practical teaching in class not only enables students to have a deeper understanding of the knowledge points,but also effectively stimulates their interest in learning this course.Statistical data show that after introducing classroom practical teaching,the average score of this course has increased from less than 80 to over 90,with an average score increase of 18.60%.The proportion of outstanding students in the comprehensive evaluation results has increased by 257.12%,reflecting good teaching effectiveness.关键词
