Designing and Evaluation of the Reduced Order IIR Filter Design for Signal De-Noising

The literature reported many fast and real-time applications such as high speed computing required to design the reduced order IIR filter designing. The major advantage of such filter designing is to reduction in computing delay and filter order. There are many methods of designing the IIR filters. In this paper one of approach is designed using the hybrid sequential combination of the band pass filter followed by the band stop filter. The prime contribution of paper is to design optimum reduced order IIR Filter and comparing the performance with the FIR filter design. In addition to review the various existing IIR filter designs. The comparative studies for different orders of the filter are presented in this paper in terms of the pass band and stop bands.
