设计有源滤波器并不一定就是一件冗长乏味的工作。只要掌握住五类最通用的二阶有源滤波器函数的基本设计指标,便可毫不费力地设计出其中任何一类有源滤波器。这五类有源滤波器是:低通滤波器、高通滤波器、带通滤波器、带阻滤波器和全通滤波器。每类滤波器用电阻和电容作为无 Designing active filters is not necessarily tedious work. As long as you master the basic design criteria of the five most common second-order active filter functions, you can effortlessly design any of these types of active filters. The five types of active filters are: low-pass filter, high-pass filter, band-pass filter, band stop filter and all-pass filter. Resistors and capacitors for each type of filter are none
