摘要 在分析心音信号特征的基础上,对心音信号进行预处理,再利用希尔伯特变换对心音信号进行心音信号包络提取,突出了心音信号的第一心音和第二心音。然后对心音包络进行分段,通过单周期心音包络的归一化能量实现了心音信号的身份识别。 In analyzing the basic characteristics of heart sound signals, the original heart sounds was preprocessed, the envelop of heart sounds was got with Hilhert transform. The first heart sound and the second heart sound were extracted. Then segregate the envelop of heart sound, identification by heart sounds was achieved through normalized energy of a single cycle of heart sound envelope .
