Filter bank spectrum analysis and application in vortex flowmeter

In this paper, the basic principle of the filter bank spectrum analysis method is analyzed. Based on this principle, a spectrum analysis method using integer coefficient filter bank is designed and applied to vortex flowmeter for vortex signal processing. The simulation results show that the proposed method can improve the accuracy of the vortex flowmeter. The simulation results show that the system can achieve efficient and accurate vortex signal processing. Spectrum analysis based on integer coefficient filter bank is a new method to process vortex flowmeter signal efficiently and accurately.
