Computed Order Tracking with Damaged Tacho Pulse

Rotating machinery can be analysed with rotation angle as the reference. This kind of reference is referred to as a tacho or key phasor, reference.  A tacho signal can be analog or digital. The end result is usually Single Pulse, a Square Wave or a train of Square Waves. Most signal analysis systems rely on the tacho pulse being in pristine condition. However, the tacho pulse may become damaged when there is sufficient vibration to shake the tacho sensor and/or the rotating system vibration is sufficient for the tacho probe to malfunction. The tacho pulse may then be damaged, and the square...
