38、时，电容充分充、放电速度快于方波变化的速度，因此能够实现方波到窄脉冲信号的转变，而且当比T 小越多时，脉冲信号宽度越窄，形成了微分电路；当方波信号的周期T 小于电路的时间常数时，电容在方波信号的一个周期内无法完成充分的充、放电，因此能实现方波到三角波的转变，而且比 T 大越多时，三角波线性越好，形成了积分电路。上面 3 中的图片可以观察到，CH1（较窄波形）的是冲激响应曲线，CH2（较宽波形）是阶跃响应曲线，冲激响应的波形更接近于脉冲信号，阶跃响应的波形更接近于方波信号。七、讨论、心得本次实验很大部分在仿真软件中完成，而事先进行仿真，让我能在试验中更快地确定电路或示波器的各种参数应该如何调整，
39、否则参数过多，很难逐一调整合适。通过观察各种电路结构的响应波形，我加深了对一阶RC电路对不同频率、不同类型信号的响应特性，也从直观上了解了微分电路和积分电路的工作原理和在不同参数下的实际工作情况。在实际操作中，为了在示波器上捕捉到完整的图像，需要调整好扫描的频率和波形放大的倍数，否则不利于观察，另外出于美观考虑在实验时可以把某些波形进行了放大（如实际操作的任务3 图的两个波形），虽然从两个频道的放大参数可以还原出实际情况，但这样的做法确实不利于直接展现两个波形的本质对比，所以在以后的实验中应该避免。文档编码:CW7H3M9I4Z4 HS4S8I9R2U5 ZC1I5K7O6A3文档编码:CW7
