DEFINITION

Classification: 375/354

SYNCHRONIZERS:

(under the class definition) Subject matter for synchronizing the operation of the receiving and transmitting mechanisms.

(1) Note. This subclass may include multiplex techniques

used to control synchronization of the transmitter and receiver; however, when the information content is multiplexed, classification is in Class 370.
