| 摘 要： | 虽然Motycka估算方法能较好地估算最大瞬时畸变值,但其估算机时很长。作者曾用40个测点,采样频率f_s=1000赫,在Inte186/330微机上估算30秒的数据,共费机时约27小时。其中约一半机时系用于对每一测点的随机数进行滤波。

| Abstract: | Fluctuating pressure filtering in Motycka method of predicting maximum instantanneous distortion is modified by instantaneous distortion filtering. Comparisonand analysis of the statistical properties of the instantaneous distortion and its maximum value with different filtering position are carried out. Relationships between the results obtained by the mentioned methods are established. It is shown that fluctuating pressure filtering in Motycka method can be modified by instantaneous distortion filtering to predict the maximum instantaneous distortion values and computing time can be greatly reduced. |
