摘要：The present invention describes an order tracking system (200) and method (100) for tracking at least one order from mechanical and/or acoustic vibrations generated by a periodic excitation process of a physical system. The order tracking system (200) comprises a means for obtaining (212) a mechanical and/or acoustic vibration data of a physical system and a means for obtaining (214) system reference data . It further comprises a means for combining (224) the mechanical and/or acoustic vibration data with the system reference data and a means for applying (226) a digital FIR filter to at least the mechanical and/or acoustic vibration data for deriving based thereon at least one order.
