High Pass
The high pass filter allows all frequencies above the specified cutoff frequency to pass
unattenuated. All frequencies below the cutoff are attenuated.
The default cutoff is 100 Hz.
Figure 25. High Pass Filter Response Curve
In figure 25, 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.
