DEFINITION
Classification: 331/45
(under the class definition) Subject matter wherein the oscillator system is provided with at least two output circuit, each output producing a separate wave of the same frequency, the waves being displaced in phase by a fixed angle (other than phase coincidence or phase opposition) so as to produce a multiphase or polyphase set of currents or voltages.
