Abstract
A microphone, coupled to the machinery under test, is connected via a blanking amplifier to a headset speaker. A sync generator, coupled to the machinery, generates a pulse each time the machinery passes through a reference position. This sync pulse sequence is the input to a phase locked loop which produces an internal representation of the instantaneous phase position of the machinery. Each time this phase position reaches an operator designated phase position, the blanking amplifier is unblanked for a duration designated by the operator so that only the operator designated segment of the machinery cycle is audible.
