Abstract
Fundamental and definition of convolution in the course of Signal Analysis and Process was introduced. From modeling analysis to realization by Matlab software,students can be led to design an echo system by themself,using the convolution technology,which can make the students grasp the essential of convolution,impulse response and concept of system. One proposed a method to make a simulated echo system by Matlab software,taking sound signals as the excitation and response of the system. From the experiment,students can hear the echo sound from systems made by their own,which can enhance their understanding to the concept of system,improve their interests to the course,and take good effect on teaching.
期刊介绍：
"Experiment Science and Technology" is a comprehensive journal of natural sciences and engineering sponsored by the Sichuan Provincial Department of Education and the University of Electronic Science and Technology of China and the Sichuan Higher Education Association. It aims to report the development status, achievements or interim achievements of scientific research in natural sciences with talent training as the center; exchange research results and experience in the design, development, function development, maintenance management and supply management of instruments and technical equipment; explore common problems in the construction of laboratories at all levels and types, team building and improving the efficiency of instrument use from a technical perspective; explore new ideas, new ways and new measures for experimental teaching reform and innovation.
The journal mainly has columns such as experimental technology, experimental teaching and teaching experiments, virtual simulation technology, laboratory environment and safety, experimental instrument development and maintenance, laboratory construction and management, and large-scale instrument management and sharing.
