A simplified design of some Cauer filters without Jacobian elliptic functions
M.D. Lutovac, D. Rabrenović · IEEE Transactions on Circuits and Systems II Analog and Digital Signal Processing · 1992
A novel treatment of the Cauer filter is presented. Rational characteristic functions, attenuation poles and zeros of the nth-order functions (n=2/sup i/ 3/sup j/, i, j=0, 1, 2, 3, . . .) are determined without using Jacobian elliptic functions and the integral. The accuracy of the results is restricted only by the precision of the calculator. Some modifications of such filters are also shown.>
