DEFINITION

Classification: 330/135

(under subclass 129) Subject matter including means to limit the maximum amplitude of the bias control voltage.

SEE OR SEARCH THIS CLASS, SUBCLASS:

11, for amplifiers having D.C.. reinsertion circuits.

138, for amplifiers with voltage delay for bias control where the bias control is not effective until a predetermined minimum voltage is reached where such minimum voltage is fixed by biasing a rectifier or control discharge device so that it will not conduct until such voltage is reached.
