High Pass
The high pass filter allows all frequencies below the specified frequency to pass
unattenuated. All frequencies above the specified cutoff frequency are allowed to pass,
while all frequencies below are attenuated.
The default cutoff is 100 Hz.
Figure 27. High Pass Filter Response Curve
All frequencies lower than the specified frequency, 100 Hz, are attenuated leaving the
upper frequency response flat. Also note at the specified frequency (100 Hz) the signal is
about 3dB down, typical operation for high pass filters.
