应用连续小波变换分析含有噪声的模拟弱信号,对比mexh、db4、coif4、haar、meyr、morl 6种小波函数,结果显示,小波函数不同所得结果也不一样.通过小波变换系数求和,可将原信号放大,mexh能有效显示所要研究的信号,峰位值不变,并且使不易进行定量分析的信号也具有良好的线性关系.

The continuous small wavelet transform was used to analyze the analog signals with noise and 'mexh','db4','coif4','haar','meyr','morl' were compared.The results showed that different wavelet functions led to different results.The original signal was enlarged through the summation of wavelet transform coefficient,and 'mexh' could effectively display research signals with unchanged peak situation,and good linear relationship for the signals which can't quantitative analysis easily.
