The high-pass resonant filter works in exactly 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.
