Abstract: A recently designed variable equalizer providing suppression and emphasis in 3 frequency bands, adjustable by means of 3 controls, and based on a different philosophy, is described. The principle features include, (1) zero insertion loss, (2) small change in apparent insertion loss as equalization is varied, and (3) more pronounced effects for equivalent changes in equalization.
