Examples
- The results show that the self - adaptive filter can be used to detect line spectrum , the wavelet transform and the fourier transform can be used to detect the ship noise in modulating the anisotropic noise field
结果表明：自适应滤波对于各向异性噪声场中的线谱检测有良好的效果；而小波变换和短时傅里叶变换对各向异性噪声场中的舰船噪声调制信号检测有良好的效果。 - Secondly , aiming to the shortage of fourier transform in analyzing unbalanced signal , wavelet transform is introduced to analyze vibration signal , example shows that wavelet analysis has excellent competence both in time and frequency region . it has good effect to combine these two methods to analyze vibration signal
其次针对传统傅里叶变换对非平稳信号分析的不足，本文将小波分析引入到振动信号的分析处理中来，实例分析表明小波分析具有良好的时频分析特性及局部化分析的能力，将傅里叶变换和小波分析相结合进行振动信号的分析处理具有良好的应用效果。
