Abstract
A method for determining the presence of a particle while actively calculating and monitoring oil debris monitor phase angle in an oil system including collecting I and Q channel data from an oil debris monitor sensor, performing a fast Fourier transform on the I and Q channel data, extracting a shape from the fast Fourier transform, and determining whether a particle is present from the shape.
