| 摘 要： | 本文提出了一种新的由两个运放、五个电容组成的有源C带阻滤波器,该滤波器能实现低通、低通带阻、带通、对称带阻网络功能,其极点参数0和Q可以独立调整。文中不但给出了实验结果和计算实例,还分析了在0点衰减为有限值的原因。

| Abstract: | A new active C notch filter circuit with two operational amplifiers and five capacitors is presented. The circuit can fulfil the second-order lowpass, band-pass, band-stop and symmetrical band-stop functions. Its pole parameters Q and (Do can be adjusted independently. Design examples and experimental results are given. It is investigated why the attenuation is not infinite at notch frequency |
