Low-speed hoist bearings are characterized by fault features that are weak and difficult to extract. Multipoint optimal minimum entropy deconvolution adjusted (MOMEDA) is an effective method for extracting periodic pulses in a signal. However. the decomposition effect of MOMEDA largely depends on the selected pulse period and filter length. https://www.roneverhart.com/SAAB-9-3-I-98-02-Frontlykt-Hoyre/
