摘要：
In order to avoid the disadvantage of low resolution of fixed-kernel time-frequency(TF) analysis, adaptive TF analysis is employed to classify cardiac murmurs including systolic murmur, diastolic murmur. The analysis results of several cases of heart disease with different cardiac murmurs indicate that the TF spectrum based on adaptive cone-kernel distribution is capable to show the power spectrum of cardiac murmurs in TF plane and the dynamic course. The TF resolution is high and the characteristics of different kinds of murmurs is obvious.
