The effectiveness for the amplitude of signal being used as the characteristic parameter has been proved by a theoretical analysis approach.

在此基础上进一步从理论上证明了信号幅值作为损伤特征参量的有效性。

Amplitude modulation is to control the amplitude of signal carrier and make it change linearly with modulation signals and maintain its frequency.

幅度调制是用调制信号去控制载波的振幅，使其随调制信号线性变化，而保持载波的频率不变。

The amplitude of signal filtered declined light not liked that the center position of energy spectrum moved to the left obviously used the highpass filter to filter.

滤波后信号幅度的衰减比较小，没有像高通数字滤波器滤波后能谱峰的中心位置有明显的向左偏移现象。

Patwari says his algorithm squares the amplitude or loudness of the signal on each link between nodes, then averages it over all 380 links.
