This research paper presents the design of symmetrical infinite impulse response (IIR) notch filter using pole position displacement. The technique of modifying the pole-zero placements has been used in order to ensure the symmetrical of the pass-band and transition-band gain. This technique was quantitative and treated by making some meaningful approximations with a set of relatively simple design equations. From the simulation, the design examples have shown the performance of the proposed method effectively.
