average

This unit samples input signals every H seconds and

outputs proportionally to an average of N numbers of

sampled data. When a new input is sampled after

another H seconds, it gives up the oldest sample and

calculates a new average including the latest sample

and outputs proportionally.

H : sampling cycle

(0.1 to 100.0 seconds adjustable)

N : number of samples to be calculated

(1 to 8 adjustable)
