WebHigh Pass Filter Summary. We have seen that the Passive High Pass Filter is the exact opposite to the low pass filter. This filter has no output voltage from DC (0Hz), up to a specified cut-off frequency ( ƒc ) point. This lower cut-off frequency point is 70.7% or -3dB (dB = -20log V OUT /V IN) of the voltage gain allowed to pass.
