137
.~.~ Oscillator supplies or controls bias
DEFINITION
Classification: 330/137
(under subclass 129) Subject matter wherein the bias voltage control means includes an oscillator which may be itself controlled by a bias voltage means and from which a signal amplifier bias voltage is derived, or from which a control voltage, usually constant, is derived.
SEE OR SEARCH THIS CLASS, SUBCLASS:
52, for amplifiers having pilot frequency control means.
130, for amplifiers including bias voltage control from a source in a system external to and independent from the amplifier. See (3) Note under subclass 130 above.
