摘要
介绍超声波在测控电路方面的2个典型应用,叙述了超声波测距电路的原理和设计原则,并介绍了它们在＂电路专题设计与实践＂综合实践课中开设的教学效果和意义。
Two typical applications of ultrasonic wave in measurement and control circuits with the focus on the operational principles of the circuits and the rules for the design are presented.The two circuits are used as the experiments for undergraduate course ＂Circuits Design and Realization for Special Topics.＂ Their significance and effects in teaching the course are presented too.
