Abstract :
A new class of equal-ripple rational functions is considered here for the design of lowpass transfer functions of RC active filters. Using a critical pole pair with a multiplicity greater than unity (as in the MUCROMAF and MUCROER polynomials), we can obtain lower pole Q-factors with this new class than with the classical Cauer functions.
