Have compared with some other methods used previously, a new one suitable for nonlinear and non-stationary digital signal sequence called HHT method is adopted to deal with the wrist pulse signals, which is an innovation in this paper.

• 在比较了前人采用的各种方法的利弊后,首先将一种新型的适用于非线性、非稳态数据处理的HHT方法引入到脉搏波信号处理中,这是本课题的特色和创新之处。
