Abstract

RIAA correction of electrical signals without the use of capacitors in a correction circuit is disclosed. A transformer is used with two or more windings, including at least two secondary windings are loaded on resistive circuits to form frequency correction. Additional inductors are installed in series with each of the secondary windings or with just one of the secondary windings.
