Abstract

It is achieved satisfactorily to realize the separation of error signals with various frequencies by numerical fitting instead of digital filtering. It is proved that both numerical fitting and digital filtering are the same in essence through mathematical reasoning. During the process of reasoning the former with the theory of the latter, a new window function is obtained of which the shape is completely different from that of traditional window functions and has never been seen before. The entire reasoning process of it is given.
