摘　　要：广义时颁表示方法在处理非平稳信号中发挥了越来越重要的作用，并在众多领域中有广泛的应用前景。本文在介绍时频分析的基本方法之后，综述了该方法在生物医学信号（如：超声多普勒血流信号、心音、心血管音、肌音、脑电及诱发电位、心电、晚电位等）处理中的应用。The methods of Generalized Time-frequency Representation have been paying an important role in nonstationary signals processing,and have been used in many fields. In this paper,we introduce the basic methods of time-frequency analysis and then review the applications of them to the processing of biomedical signals,including heart sound,cardiovascular sound,muscle sound,EEG,EP,ECG and LECG.
