When processing the signal from an inductive pulse generator used to measure shaft rotational speed, which of the following is used to process the signal to an rpm value?
A) DC voltage
B) AC voltage
C) Amperage
D) Frequency

Question

Quizplus · Accepted Answer

The signal from an inductive pulse generator, which varies with the rotational speed of the shaft, is essentially a frequency signal. The number of pulses per unit time (frequency) is directly proportional to the rotational speed, and thus, processing this frequency allows for the calculation of revolutions per minute (rpm).
