The analysis of harmonic is an important subject for environment government of power system. It is necessary that the signal of sampling will be processed by the filter,in order to improve the precision of harmonic analysis. Window function is considered to be the simplest method in designing FIR Digital Filter. The performance of FIR digital filter can be improved by choosing the suitable window function. The FIR digital low-pass filter designed in this paper has more advantages in practice,through the improvement of the gauss window function. The simulated results show the effectiveness of the proposed method.
