Although traditional processing method of modulus maximum array can retain characteristics of signal, the signal after de-noising exists thorns and slight oscillation at singularity point.
传统的模极大值序列处理方法虽然可以保留信号特征,但降噪后的信号在奇异点有毛刺和轻微的振荡。
Based on the principle of modulus maximum, a new approach using scalogram of wavelet transform for transient signal, under noise free condition or noise condition separately, is described.
利用小波变换模极大值原理,提出了用小波变换尺度谱检测瞬态信号波至点的新方法,研究了其检测无噪声和有噪声条件下的瞬态信号的能力。
