The difference of base function cause the difference of observation angle and observation method for signal , this is the essence of wavelet transfer differentiate fourier transfer f short - time fourier transfer , comparing performance and characteristic of various wavelet base functions in common use in fault diagnosis and studying inner connection of different fault diagnosis signal and various wavelet base functions , it is pointed out that genuine optimum wavelet transfer is that signal decompose of base function should be most close to and be most suited to signal feature
基函数的不同导致对信号观测角度和观测方法的不同，这是fourier变换、短时fourier变换和小波变换的本质区别。通过比较故障诊断中常用的各种小波基函数的性能和特点，研究不同的故障信号特征与各种小波基函数的内在联系，指出真正的最优小波变换应该是根据信号特征与其最近似、最匹配的基函数的信号分解。
