1、WhenV_{in}=sin(2\pi f_{m}t), what is the phase shift of Vin through this RC filter? 笔者的思考:这题则是对于实际电路情况的考察。之前都是在time domain去思考整个一阶RC滤波器,现在的话就是从frequency domain去想,去思考一个小信号的相移如何?
选频电路(滤波器)允许某些频率的信号从输入传输到输出,IRFP90N20DPBF同时阻止所有其他频率的信号。也就是说,在理想状态下,除了已选择频率外的所有频率分量都将被滤掉。 串联RC电路展示了一种选频特性。有两种类型串联RC电路。要分析的第一种是低通电路(low-passfilter),和在相位滞后电路中一样,它是通过从电容上取...
