1. A vibration monitoring system comprising:
a plurality of encoders configured to generate a plurality of pulse train signals for a plurality of wheels, wherein each of the plurality of encoders is coupled to a respective one of the plurality of wheels and generates a single one of the plurality of pulse train signals; and
an analyzer coupled to the plurality of encoders and configured to
generate both a plurality of pulse per revolution signals and a plurality of angular velocity signals for the plurality of wheels in response to the plurality of pulse train signals, wherein each of the plurality of pulse per revolution signals conveys a single pulse per rotation of the respective wheel,
generate an input phasor array as an n×p array that organizes a plurality of input phasor quantities of the plurality of pulse per revolution signals caused by the plurality of wheels, wherein n represents a plurality of extracted points from each of the plurality of pulse per revolution signals, and p represents the plurality of wheels,
generate a response phasor array as an m×p array that organizes a plurality of response phasor quantities of the plurality of angular velocity signals caused by the plurality of wheels, wherein m represents a plurality of extracted points from the plurality of angular velocity signals, and
generate a report that identifies at least one vibrating wheel of the plurality of wheels in response to the input phasor array and the response phasor array.
