摘要:
Experimental investigations were made of the covariance structures of the envelope functions of several nonstationary reverberation processes. It is shown that, when the process is stationary, the covariance of the envelope is approximately equal to the square of the envelope of the covariance of the narrow‐band process. However, when the nonstationarity of the reverberation process becomes noticeable, then this simple relationship is no longer valid.
