Errors Considered in the FFT Spectrum Analysis

Lu Shuang Han Lianying(Department of Mechanical Engineering, Jilin Institute of Technology, Changchun 130012) Zhao Bin(Second Machine Tool Factory of Changchun)  
Based on the essence of fast Fourier transformation, the main errors encountered in the quantizing distortion in A/D converting, as well as the leakage effect, aliasing effect and railing effect in signal spectrum analysis are discussed. The corrective measures in various conditions are proposed.
