有源低通滤波器有哪些

有源低通滤波器是一种常见的滤波器类型。它允许低频信号通过，同时衰减或抑制高频信号。有源低通滤波器通常由运算放大器和电容器组成。在有源低通滤波器中，运算放大器的增益和电容器的数值可以根据具体需求来选择。常见的有源低通滤波器设计包括Butterworth滤波器、Chebyshev滤波器和Bessel滤波器等。其中，Butterworth滤波器的特点是通频带的频率响应曲线最平滑。因此，在要求通频带内增益约11dB、对特定频率的信号进行滤除的情况下，选择Butterworth滤波器是一个不错的选择。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
