Amplitude modulation occurs often in vibration signals generated by rotating machines. It is usually recognized by the presence of sidebands in the vibration spectrum. The most common modulating frequency is the turning speed, or 1X vibration component, and common modulated frequencies are gear mesh and bearing tones. See also Demodulation.
