Constant-Q Graphic Equalizers

A new class of graphic equalizers is presented that is characterized by being constant-Q and shown to offer significant advantages over conventional RLC and gyrator based designs. Only constant-Q designs are, in fact, true "graphic" equalizers. Included is an introductory tutorial on the design requirements and trade-offs of constant-Q circuitry, as well as a discussion regarding the combining characteristics of each class of equalizer. Shown is that all equalizers combine equally for the same bandwidths. Finally, areas requiring future research are outlined and discussed.
