利用高斯小波的线性特性和带通特性,设计小波滤波器组.运用该滤波器组对调制信号进行解调分析,实现了选频、可变带宽包络分析.将传统的包络分析中信号的窄带带通滤波和包络分析结为一体.算法具有较强的适时性,为包络分析提供了一种新方法.
By using the linear characteristic and band-pass characteristic of Gaussian wavelet, a wavelet filter bank is designed.Using the filter bank to demodulate and modulate the modulated signal, the frequency-selective and variable-bandwidth envelope analysis is realized.Traditional envelope analysis signal Band-pass filtering and envelope analysis.The algorithm has strong timeliness and provides a new method for envelope analysis.
