DEFINITION

Classification: 343/814

(under subclass 812) Subject matter including a passive network (which may be resistive, inductive or capacitive or any combination thereof) for transmitting signal energy between the doublets and a source or a receiver of such signal energy.

(1) Note. For an explanation of the terms used in the above definition and distinctions between coupling and tuning subclasses, see (1) to (4) Notes under subclass 850, below.
