[Uniformity] Harmonic Computation

A force variation waveform can be broken down into an infinite number of harmonics. The ASTEC® Computer computes the 1st through the 10th harmonic. Both the harmonic amplitudes and angles are available in the TIGRE™ program for display and recording.

Note: Generally, the 1st and 2nd harmonics of force variation influence the ride quality of a vehicle the most.
