The purpose of IIR notch filter is to remove Narrow Band Interference signal while leaving Broad Band Signal unchanged in communication system. This research paper presents a method for design of fixed notch filter at center frequency FO (90MHZ). The authors calculate two parametric values like pass band ripple &stop band attenuation by using mathematical modeling. For this purpose, they have selected elliptic design method, direct form II transposed SOS algorithm. Bandwidth ranging from 0.2GHz to 200 MHz has been generated with the help of different RF & AF oscillator.
