本文提出一种新的由一个运放、一个电容和几个电阻组成的有源滤波器电路。该电路充分利用了运放的极点
能实现低通、高通、带通、带阻和全通网络功能。作为带阻滤波器时
不仅能独立地调节ω
0
与Q
并能调节阻带衰减。文中给出了计算实例与实验结果。
A new active filter circuit with one operational amplifier.one capacitor and several resistors is presented.The operational amplifier pole is utilized. The circuit can fulfil the second-order lowpass
highpass
band-pass
band-stop and allpass functions. As a band-stop filter
not only the w0 and Q can be adjusted independently
the band-stop attenuation can also be adjusted. Design examples and experimental results are given.
