Autors: Anzova , V. Title: LOW SENSITIVITY DESIGN OF MULTIPLIERLESS ELLIPTIC IIR DIGITAL FILTERS Keywords: IIR digital filters, allpass sections, low sensitivity, multAbstract: In this paper an improved method of design of low sensitivity multiplierless elliptic IIR
digital filters is proposed. The design technique is based on the sensitivity analysis and a selection of proper allpass sections. The allpass sections used to realize the allpass structures
are with minimized sensitivities. Using the symbolic analysis, the expressions for phase
sensitivities to multiplier coefficients for the selected allpass sections have been derived. The
amplitude sensitivities of the obtained realizations have been investigated. The comparison
between the resulted digital mul References - Milic, L.,Lutovac, M.,, 1999, Signal Processing: Design of multiplierless elliptic IIR filters with a small quantization error, , Feb.1999, <>, IEEE
