| Abstract: | A real time processing system based on a digital signal processor is described in this paper, and the signal frequency of vortex flowmeter is computed by means of an adaptive notch filtering method. There is only one parameter to be estimated in the adaptive notch filter. This system process signals in real time, and the system is small sized because it adopts a DSP. The testing results indicate that the adaptive notch filtering method and processing system are efficient. |
