摘　　要：在本校"地方性、应用型、工程化"人才培养目标的办学理念下,对通信原理课程进行工程化教学方法的探索和实践。在课堂教学过程中,把语音作为工程信号,课堂上现场进行语音信号的FM调制与解调工程化教学。通过现场仿真波形图和语音回放的方式分析语音信号通过调频系统后的变化。课堂效果证明,学生学习该课程的兴趣较以前有很大的提升,同时也增强了教师的工程化教学理念,为如何将电子信息类课程进行工程化教学改革提供了一个有效的途径。Under ＂the local, application type, engineering＂ of educational philosophy engineering exploration and practice of teaching methods of Communication Theory are studied .In the classroom to FM modulation and demodulation is demonstrated based on the speech signals through simulation. Those waveforms and voice replayed are analyzed by students. The results proved that students are interested in this course greatly, but also the teacher＇s teaching ideas is improved. It is an effective way for teaching reform of other curriculums.
