Low Pass Filter
A filter with a characteristic that allows all frequencies below a specified rolloff frequency to pass and attenuate all frequencies above.
In general, the final rate of power rolloff for an order-n all-pole filter is 6n dB per octave (i.e., 20n dB per decade).
An anti-aliasing filter is an example of a low pass filter.
Also known as a high-cut filter.
