High Pass
The high pass filter allows frequencies below the specified frequency to pass 
unattenuated. All frequencies below the cutoff are attenuated.
The default cutoff is 100Hz.
Figure 26.  High Pass Filter Response Curve
All frequencies lower than the specified frequency (in this example,100 Hz) are attenuated 
leaving the upper frequency response flat. Also note that at the specified frequency 
(100Hz) the signal is 3dB down, typical operation for high pass filters. The 3dB down 
point will remain constant regardless of the slope setting. Only the steepness of the 
frequency attenuation curve changes.
