摘　　要：将传统的脉冲信号的产生与整形章节的内容进行大的改革，从555定时器入手讲解单稳态触发器、施密特触发器和多谐振荡器，使该章节的内容简单明了。这种方法保持了数字电路教学方法的一致性，对理解脉冲信号的产生和整形的原理有很大的帮助。The reforms are largely done to the section of pulse generator and pulse shaper, starting from 555 timer to explain one-shot trigger, Schmitt trigger and multi-harmonic oscillator, so that the contents of the section are simple and clear. The teaching methods maintain the consistency of digital circuit technology and make great help to the understanding of the principles of pulse signal generation and shaping.
