摘要
本文用了一种新的方法推导了偏相干函数的计算,主要讨论有三个和四个信号的情况下偏相干函数的计算公式。文中所讨论的偏相干函数计算方法,物理意义清楚,计算简单。最后还给出了将这一方法应用于空压机声源识别的结果,其结果是令人满意的。
In this paper, a new method is applied to get the computation formula of partial coherence function. The main attention is paid to the computation formula of partial coherence function with three and four signals. The advantages of the method discussed in the paper are clear in physical meaning and easy to compute. At the end of the paper, the application of the method to the identification of an air compressor noise source is presented and the result is satisfactory.
