DEFINITION

Classification: 363/13

CURRENT CONVERSION:

(under the class definition) Subject matter wherein the conversion system includes means to convert alternating current to direct current or direct current to alternating current.

(1) Note. The conversion systems included in this and the indented subclasses are the current conversion systems as defined in the class definition.

(2) Note. In the communication arts, there are many different conversion systems which are, in fact, converters of D.C. to A.C. or vice versa. A partial list of such converters includes oscillators, detectors, amplifiers, demodulators, etc. See the class definition, Lines With Other Classes, for more detailed discussion of the conversion systems not included in this class. See the class definition, References to Other Classes, for a listing of the related art.

1+, for current conversion systems cascaded or combined with frequency or phase converters without intermediate conversion to D.C.
