摘　　要：结合教学实际,在《信号与系统》课程中进行了工程化教学方法的探索和实践。借助多媒体和MATLAB仿真软件,通过在课堂上对各种男女生语音信号进行现场采集、现场处理、现场演示的教学方式来增强学生对课程中理论部份的理解和分析能力。教学效果显示,不但提高了学生们的学习兴趣,更重要的是培养了学生理论联系实际的工程化思想,为学院提高应用型本科人才培养质量提供了一个有效的途径。Combined teaching ideas,engineering teaching method was practiced in Signal and System course in order to promote engineering teaching reform. With the multimedia and MATLAB software in the classroom a variety of male and female students＇ voice signals were collected and processed and demonstrated at the scene to evance the students＇ analytical capabilities on the principles of course. It showed that not only the students＇ interest was improved,but also the students＇ engineering ideas were integrated and practiced. It provides an effective way how to improve the quality of application-oriented personnel trainings.
