**Smooth g
RC Filter g
Low Pass**

Applies a RC Low Pass filter using the following formula:

Y Alpha = DT / (RC + DT) DT = X |

**Smooth g
RC Filter g
High Pass**

Applies a RC High Pass filter using the following formula:

Y Alpha = RC / (RC + DT) DT = X |

For both filters you only have to specify the RC factor. Alpha is calculated for each datapoint separately, using the X-distance of the current datapoint to the previous datapoint. For a correct sample frequency calculation X needs to be in seconds (X=6 means t = 6 seconds).
