Abstract :
A method for realizing second-order digital filter structures that are amenable to error-spectrum shaping was proposed recently by P.S.R. Diniz and A. Antoniou (see ibid., vol.CAS-32, p.1000-7, 1985). this method minimizes the noninteger multiplier values for identifying the low-sensitivity structure. An alternative approach based on the concept of pole-sensitivity is presented for identifying the optimum structures. The two methods are compared. It is found that the proposed method is applicable for any pole location and eliminates the need for a separate sensitivity analysis
