Transmission characteristics of Gaussian filter and spline filter may differ from used at actual sites.
- class="label">•
In case of SF, theoretical characteristics are periodic SF's. Nonperiodic SF's are unknown. In case of GF, filter width is different.

We solve problem that it was impossible to calculate the transmission characteristics that is used at actual sites.
- class="label">•
Transmission characteristics of the GF of filter width λc were almost the same as theoretical.
- class="label">•
Transmission characteristics of the nonperiodic SF were different from theoretical and not to be unique.
