Differentiator Channel

Overview

Differentiator channels are used to create an output that is the differential of an input with respect to time; i.e. the gradient or rate of change of the input value.

Differentiation is the inverse of integration (see Integrator Channel ). Given an input like Distance Travelled, the rate of change may be computed to give an approximation of the Speed.

Computing differentials using the first difference alone can result in a very noisy looking signal.

The average slope over the last Window seconds is therefore computed.

Acceptable values are between 0.1 and 2.0 seconds.

Higher numbers will produce a smoother, more filtered output but with a slower response time.
