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

减少采样点的数量进行了检查，以找到更好的方法来计算2-D离散菱形频率分布。结果表明，对于二维菱形频率分布，可以找到一种使采样点数等于所需频率分量个数的采样方法，而对于三维菱形频率分布，该方法不适用。然后，抽样方法，其中的采样点的数量可以减少，因为我们可以，检查。结果表明，找到了一种采样点数与所需频点数之比约为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.
