有源语音滤波器在线计算器
可以帮助您设计各种类型的有源滤波器，包括低通、高通、带通和带阻滤波器等。您需要提供一些基本参数，例如通带截止频率和阻带截止频率，该工具将根据这些参数自动生成滤波器设计方案。
Instructions for use: Please select the type of filter you want to design (Qualcomm, Low Pass or Bandpass Filter). Click [Display Circuit Diagram] to display the circuit schematic;
Input parameters: voltage amplification factor; filter cutoff frequency in HZ; capacitance C2 value in nF. When you design a bandpass filter, enter the filter bandwidth you want to design in the bandwidth box.
