Abstract :
A method is given to determine the coefficients of a modified lowpass maximally flat (at the origin) Butterworth polynomial, with a reduced dominant-pole-pair Q factor at the expense of increasing order of the transfer function with multiplicity of the dominant pole pair greater than one.
