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 100 Hz.
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
(100 Hz) the signal is 3 dB down, typical operation for high pass filters. The 3 dB down
point will remain constant regardless of the slope setting. Only the steepness of the
frequency attenuation curve changes.
