图1.4 Sallen-Key低通滤波器的波特图 二、高通滤波器(HPF:High Pass Filter) 图1.5,Sallen-key高通滤波器(HPF)实例 有了上文的介绍及计算公式的推导,此处的计算就显得轻车熟路了。首先,将图1.5的电路中的实际阻容器件转换为阻抗z。 代入公式1.5,得到公式1.8: 将实际的数值代入公式1.9,得到公式1.9: 使用仿真软...
Sallen和Key High Pass滤波器 然后截止或转角频率为200Hz,通带增益为2.667,截止频率为8(2.667 * 3)时的最大电压增益= 3,我们可以在下面的Bode图中显示这个二阶高通Sallen和Key滤波器的特征。 Sallen和Key Filter Bode Plot Sallen和Key Filter Summary 我们在本教程中已经看到Sallen-Key配置,也称为电压控制,电压...
In one implementation, the dynamic bass equalization circuit includes a Sallen-Key high pass filter that includes an amplifier with a negative feedback path. The dynamically adjusted frequency response is provided by a parallel pair of reversed diodes connected in the negative feedback path.Anderson,...
