The low pass filter can be used to filter out undesired high frequencies.
| • | Gain K: The filter gain K determines the low frequency gain of the filter. |
| • | Frequency f: The filter roll off starts at frequency f in Hz. Lower frequencies will pass the filter, higher frequencies will be filtered out. |
| • | Quality Q: The filter quality indicates how steep the phase response will decrease at the frequency f. A quality Q > 0.707 results in a peak in the magnitude response at frequency f. |
