Proposal of an efficient frequency analysis to evaluate the characteristics of electronic circuits and its application

研究了采样点数目的减少，以寻找更好的方法来计算二维离散的钻石形状的频率分布。因此，对于二维钻石形频率分布，可以找到一种采样点数等于所需频率分量的采样方法，但这种方法不适用于三维钻石形频率分布。然后，研究了尽可能减少采样点数量的采样方法。结果表明，可以找到一种采样点数与所需频率点数之比约为1.15的采样方法。

The reduction in sampling-point numbers was examined to find better methods to calculate the 2-D discrete diamond-shaped frequency distributions. As a result, a sampling method, where number of sampling points can be made equal to that of necessary frequency components, can be found for 2-D diamond-shaped frequency distributions.However, this method is found not to be applicable to 3-D diamond-shaped frequency ones. Then, the sampling method, where the number of sampling points can be reduced as possible as we can, are examined. The results show that a sampling method, where the ratio of the number of sampling points to that of necessary frequency points is about 1.15, is found.
