DEFINITION

Classification: 322/96

(under subclass 95) Subject matter wherein the generator armature control is by means of a plurality of impedances in circuit with the armature.

(1) Note. The plurality of impedances must be different impedance elements. A tapped or sectionalized impedance element is not a plurality of impedances.
