there is no emphasis around the cutoff frequency and the attenuation is -3dB
at the cutoff frequency. The attenuation for frequencies located above the
cutoff frequency depends on the order of the filter which is set by the
Order
menu, a slope of -12dB/Oct corresponding to a second order filter and a slope of -24dB/Oct to a
fourth order filter.
Resonant High-Pass Filter
Figure 23: Frequency response of the high-pass filter.
The high-pass resonant filter works exactly in the opposite manner as the low-pass resonant
filter by removing the frequency component of a signal located below the cutoff frequency while
leaving those above the cutoff frequency unchanged. Similarly to the low-pass filter, the
Q-factor
controls the emphasis of frequencies located around the cut-off frequency.
