Overview
Linear Smoothing with separate Up/Down time constants
Discussion
This module restricts the rate of change of a signal in a linear fashion. It computes the steps by calculating the delta between the current and the target value and its rate defined by a time constant. Different smoothing times for up- and down stepping can be defined.
