It is shown that modified all-pass filters can be utilized to further equalize a complex system by purposely introducing and characterizing error in pole-zero locations. In audio systems requiring magnitude and phase manipulation, filter order can be reduced using this approach. Design formulas will be presented which describe these attributes in terms of classical filter parameters, functions, and formulas. Both analog and digital theory and applications are presented.
