摘要
该文首先对FFT谱分析的几个基本问题进行探讨,然后用此方法对应力式涡街流量计的实际信号进行处理,并分析了此方法用于低频信号处理时的优缺点.
This paper presents a method of FFT spectral analysis in vortex signal processing. Several key problems of the method are first discussed. Then, a real vortex signal is processed using the spectral analysis. Based on the experimental results the advantage and disadvantage of FFT spectral analysis in processing signals at low frequencies are summarized.
