DEFINITION

Classification: 327/327

Using only transistor active elements:

(under subclass 309) Subject matter wherein the limiting, clipping, or clamping utilizes a three or more terminal solid-state device as the sole active circuit device type.

SEE OR SEARCH THIS CLASS, SUBCLASS:

310+, for limiting, clipping, or clamping to reduce unwanted noise signals.

315+, for circuits providing constant input-output ratio level.

574+, for special three or more electrode solid-state devices and circuits, per se.
