经典时域分析方法
经典时域分析方法-
最终在权衡速度与准确率两方面的情况下，选择了经典的时域分析方法。
Finally , the typical time-domain method is chosen by tradeoff between the processing speed and the detection accuracy .

生物信号的非平稳特性使得经典的时域分析方法和频域分析方法不能更好地描述信号的局部特征，而联合时频表示可以有效地反映信号的瞬时频率特性。
Other than the traditional analysis methods merely on time domain or frequency domain which are unable to describe the local characteristics of the biological signals properly due to their nonstationarity , the joint time-frequency representation can illuminate the transient frequency characteristics os signal effectively .
