By this we can say that for every tenfold (decade) increase of frequency the gain of the voltage is divided by 10. You can also manually drag the sliders and enable the 2 Pass filter. I need low pass and high pass filter written in c#. L1 is 100 ohms and C1 and C2 are also both 50 ohms. The low-pass filter has a gain response with a frequency range from zero frequency (DC) to ω C. low pass filter vlc
