| Abstract: | The wavelet transformation method is used to analyze the characteristics of measure data.The data were obtained from the sensors installed on the wings of the flying airplane.The frequency characteris tics resulted is given out.The method is compared to the traditional FFT(Fast Fourier Transformation)analysis.The feasibility of analyzing the engineering measure data using wavelet transformation is discussed in this paper. |
