Abstract:
A method for analyzing a physical system having one or more rotating elements, the method comprising:receiving measurement information for a physical signal generated by the physical system, wherein the measurement information includes information indicating a plurality of order components of the physical signal, and wherein the measurement information does not include rotation speed information; processing the measurement information to create time frequency plot information for the physical signal; displaying the time frequency plot information on a display, wherein the time frequency plot information includes a plurality of points visually indicating the order components of the physical signal; receiving user input selecting one or more of the visually indicated order components; performing one of: a) creating a time domain signal in which the one or more selected order components are suppressed; or b) creating a time domain signal consisting of the one or more selected order components; and presenting the time domain signal to a user on a presentation device; wherein the time domain signal is useable in analyzing the physical system having one or more rotating elements.
