Number: 327/141
Name: Miscellaneous active electrical nonlinear devices, circuits, and systems > Signal converting, shaping, or generating > Synchronizing
Description: Subject matter wherein a signal is produced which will (a) maintain a predetermined phase or frequency relationship between two sources of waves, one source being an excitation or standard source (sync source) and the other source being changed to achieve the predetermined relationship; (b) provide an initiate or stop operation to a device at a predetermined time; or (c) time (i.e., synchronize) the operation of some electrical circuit or system.
