摘要：
In this Note the vortex sensor signal is modeled as a narrow band process, and the frequency of the vortex sensor signal is measured by the means of adaptive notch filtering. A real time processing system based on a digital signal processor is developed. The testing results show that the adaptive notch filtering method and the processing system are effective for vortex flowmeters. (C) 2001 American Institute of Physics.
