Extron electronic DMP 44 LC manual High Pass, Low Pass

Page 26

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.

High Pass

The high pass filter is the opposite of the low pass filter. All frequencies below the specified frequency are attenuated allowing higher frequencies to pass.

In the figure below, the frequencies lower than the specified frequency, 1 kHz, are attenuated leaving the higher frequency response flat.

Figure 13. High Pass Filter Response Curve

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.

In the figure below, the frequencies higher than the specified frequency, 10 kHz, are attenuated leaving the lower frequency response flat.
