The filter is removing everything below the cutoff from the signal. Roll-Off Filters are not always perfect. They can let a portion of the signal beyond the cut-off frequency through. In the case of our high-pass filter example above, you can see that some of the signal is “leaking by” past the cutoff point near the steep slope.

This is fairly representative of the actions of filters called “Sharp Roll-off” or “Fast Roll-Off”. Basically, these prioritise a flat frequency response (and, as we’ll see, reduced ultrasonic artefacts). Filters 2 and 4 start rolling off earlier, down by nearly 0.1dB at 10kHz, 3dB at around 17kHz and -5dB by the time it gets to 20kHz.
Anyone knows what a "DAC filter roll-off" is?

This requires a low pass filter, and that filter has some kind of roll-off characteristic between the pass band and the stop band. Some idealise the filter as having a perfect brick-wall cutoff -- an instantaneous transition from pass to stop levels -- and the best approximation of that is the steepest roll-off you can manage.
