(under the class definition) Subject matter wherein the amplifying device is a saturable magnetic core with at least means to apply an electrical signal and an A.C. power supply to at least one winding thereon; the input signal which may be D.C.. or A.C. is applied to the signal winding to control an A.C. power supply applied to the power winding, which may be the same winding or a different winding.
(1) Note. To be classified in this class the signal output of the amplifier must be a substantial replica of the input signal. Therefore subject matter involving saturable reactors without filter means is not classified in this class with amplifiers, but is classified elsewhere. See the SEarch Class: notes below. Subject matter involving saturable reactors claiming a "demodulator" and disclosing a filter therewith but not claiming the filter are assumed to claim the filter as part of the demodulator and are classified herein.
