摘要
目的 :为了更直观全面地分析心音信号。方法 :引入JTFA方法,利用LabVIEW2011进行编程设计,以实现将一维的心音信号图变化为综合的强度图谱形式。结果 :成功使用所设计的程序实现对心音信号的直观分析。结论 :采用上述方法能从另一个方面优化对心音信号的分析。
Purpose：We do it to intuitively and roundly analyze heart sound signals.Method：We recommend JTFA method,then design the programs by the way of LabVIEW2011,at last we realized to change one-dimensional heart sound signals into the form of synthesized intensity maps.Result：We have successfully used programs to realize intuitional analysis on the signals.Conclusion：Using the method described above can improve the analysis on heart sound signals.
