DEFINITION

Classification: 327/365

GATING (I.E., SWITCHING INPUT TO OUTPUT):

(under the class definition) Subject matter wherein one signal (a controlling signal) determines whether an input

signal is transmitted without modification to an output or is blocked therefrom.

(1) Note. The input signal may be a DC, AC, or a complex wave in the switching operation.

(2) Note. Excluded herein are switching systems including those which are solely mechanical or electromechanical (either static or dynamic) and those handling high current or voltage.

(3) Note. Switching circuits or systems peculiar to an art device are classified with the art device. For example, a centralized telephone switching system is classified in Class 379, subclasses 242+.

SEE OR SEARCH THIS CLASS, SUBCLASS:

124, for signal waveform generating by periodic switching (e.g., chopping).

337, for an integrator which utilizes the switching of a capacitive arrangement. 554, for an adjustable filter which utilizes the switching of a capacitance into or out of the circuit.
