WebTheory 2 nd Order High Pass Filter. High Pass Filter :-The basic operation of an active high pass filter is exactly the same as that for its equivalent RC passive high pass filter circuit except this time the circuit has an operational amplifier included within its filter design providing amplification and gain control. A high-pass filter (HPF) is an electronic filter that passes signals with a frequency higher than a certain cutoff frequency and attenuates signals with frequencies lower than the cutoff frequency. The amount of attenuation for each frequency depends on the filter design.
