Patent ID: 11168612

Abstract:
Herein provided is a signal processing device for use in an aircraft engine with a variable geometry mechanism (VGM) and associated systems and methods. The signal processing device comprises a processing unit and a non-transitory computer-readable memory communicatively coupled to the processing unit. The memory has stored thereon computer-readable program instructions executable by the processing unit for: obtaining a VGM position request signal; determining whether a variation of the VGM position request signal is within a predetermined range; when the variation of the VGM position request signal is within the predetermined range: filtering the VGM position request signal to reduce a level of noise in the VGM position request signal; and transmitting the filtered VGM position request signal; and when the variation of the VGM position request signal is not within the predetermined range, transmitting a processed signal, based on the VGM position request signal.
