由于这个电路让频率较低的信号容易通过,我们称此电路为低通滤波器低通滤波器(Low-pass Filter, LP);相对的也有些电路让频率较高的信号通过,我们称此电路 16、为高通滤高通滤波器波器(High-pass Filter, HP);如果只让中频信号通过,我们称此电路为带通滤波带通滤波器器(Band-pass Filter, BP)。请看以下图:...
过去的滤波器都是由R、L、C等无源元件组成,称为无源滤波器。现在的滤波器大都是由R、C元件与有源器件(如运算放大器)组成,称为RC有源滤波器。 常见滤波器类型有低通滤波器、高通滤波器、带通滤波器、带阻滤波器、全通滤波器等。 RC有源带通滤波器 ...
