The purpose of analysis and optimization of fixed notch filter is to remove narrow band interference signal while leaving broad band signal unchanged in communication system. This paper presents a method for design of digital fixed notch filter at center frequency FO (90MHZ). Several parametric values such as pass band attenuation, stop band attenuation are calculated by using mathematical modelling. For this purpose the authors have selected elliptic design method, direct form II SOS algorithm. Q's-factor in the range of few Q
