Partial Equalization of Non-Minimum-Phase Impulse Responses

Partial Equalization of Non-Minimum-Phase Impulse Responses

<p/> <p>We propose a modified version of the standard homomorphic method to design a minimum-phase inverse filter for non-minimum-phase impulse responses equalization. In the proposed approach some of the dominant poles of the filter transfer function are replaced by new ones before carr...
