Traditional methods of interference reduction in the wigner distribution are based on linear filtering. Recently a new approach of nonlinear filtering was developed. The filter's behavior varies from an identifier to a low pass filter depends on the region of operating. This filter has a very good response which dos not effect on the resolution and concentration of auto-terms. But in the cases which the time and frequency distance is not enough it can not perform very well. In this paper we tried to show this lack of proposed filter and find the regions where can assure us about accurate operation of this filter.
