Abstract
This paper proposes a variable-Q digital graphic equalizer in which each equalizer filter has different Q-factor depending on the band as well as the gain. The proposed equalizer demonstrates the symmetric frequency response over the audible frequency range. While maintaining the similar level of hardware complexity, the proposed equalizer yields an actual response that is quite close to the desired one, as compared with the conventional equalizers. Also, we investigate how the performance is affected by the center frequencies of the filters.
