Low Pass - Extron electronics DMP 64 User Manual

The parametric filter allows frequency selection accurate to 0.1 Hz and either 6 or 12 dB
of slope. Notice 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 will change.

Low Pass

The low pass filter is the opposite of the High Pass filter. All frequencies above the
specified frequency are attenuated allowing lower frequencies to pass.

Low Pass Filter Response Curve
Here, the frequencies higher than the specified frequency, 10 kHz, are attenuated leaving
the lower frequency response flat.
