摘要
本文以8音阶简易电子琴电路引入,从信号产生和8音阶实现两个问题入手,引出RC正弦波振荡电路理论,并拓展应用到实现简易电子琴的设计。通过全员参与,步步设疑,层层探究,理论与应用结合,激发了学员兴趣,提高了学员能力。
Begin with a simply interesting electronic organ,a multicomponent teaching method is proposed to intxoduce RC sine wave oscillator.Signal generator and 8 musical scale design are main problem.With the completion of the electronic organ,the theory and application of RC sine wave oscillator is grasped.In this process,everyone joins in the process to solve and do research for series of problem which the teacher designed.The multicomponent teaching method is good for the students to develop their interests and capability,
