These have names like “Slow Roll-off” and “Smooth Roll-off”. At this point I will note that a lot of reviewers profess to prefer the sound from this Slow/Smooth kind of filter. Standing by itself is Filter 5.
WebA high-pass active filter with a roll-off -20 dB/decade is shown in Figure. Notice that the input circuit is a single high-pass RC circuit. The negative feedback circuit is the same as for the low-pass filters previously discussed. The high-pass response curve is shown in Figure 15–13(b).
