Bearing faults of rotating machinery are observed as impulses in the vibration signal, but it is mostly immersed in noise. In order to effectively remove t... AS Raj,N Murali - 《IEEE Transactions on Industrial Electronics》 被引量: 122发表: 2013年 Horizontal head impulse test detects gentamic...
A first transmitter/receiver unit (TRU) (1) transmits at a relatively low first frequency (f1). A second TRU (2) transmits at a higher second frequency (f2). During transmission, both first and second TRUs are synchronized in time as they operate. Evaluating signal runtime between first ...
