Abstract

This paper proposes an adjusted-Q digital graphic equalizer employing the opposite filters.-A method for designing the proposed equalizer is also presented. In the proposed adjusted-Q equalizer, we adjust the Q-factor of the equalizer filter depending on the gain, yielding an improved equalizer performance. Also, by increasing the Q-factor of the opposite filters gracefully with increasing gain, the inter-band interference can be reduced effectively in all frequency range in consideration. We shall show that the proposed equalizer can reproduce the user's gain setting faithfully.
