<short_desc>Cutoff frequency for the low pass filter on the D-term in the rate controller</short_desc>
<long_desc>The D-term uses the derivative of the rate and thus is the most susceptible to noise. Therefore, using a D-term filter allows to decrease the driver-level filtering, which leads to reduced control latency and permits to increase the P gains. A value of 0 disables the filter.</long_desc>
