A bit used to achieve or maintain synchronism.
Note: The term "synchronization bit" is usually applied to digital data streams, whereas the term "synchronization pulse" is usually applied to analog signals.

In digital systems, a sequence of bits introduced into a transmitted signal to achieve or maintain synchronism.

A pulse used to achieve or maintain synchronism.
Note: The term "synchronization pulse" is usually applied to analog signals, whereas the term "synchronization bit" is usually applied to digital data streams. Synonym sync pulse.

1. Achieving and maintaining synchronism.
2. In facsimile, achieving and maintaining predetermined speed relations between the scanning spot and the recording spot within each scanning line.
Note: In the civilian community, the noun "synchronization" is preferred to "synchronizing. "

In FDM, a reference frequency used for achieving and maintaining syntonization of the oscillators of a carrier system or for comparing the frequencies or phases of the signals generated by those oscillators.

In facsimile systems, the signal that maintains predetermined speed relations between the scanning spot and recording spot within each facsimile scanning line.

1. Pertaining to the relationship of two or more repetitive signals that have simultaneous occurrences of significant instants.
Note: "Isochronous" and "anisochronous" pertain to characteristics. "Synchronous" and "asynchronous" pertain to relationships.
2. Pertaining to synchronism.

[A] method of on-line crypto-operation in which crypto-equipment and associated terminals have timing systems to keep them in step. [INFOSEC-99]

In a data network, a bit-oriented protocol for the control of synchronous transmission over data links.

A data network in which synchronism is achieved and maintained between data circuit-terminating equipment (DCE) and the data switching exchange (DSE), and between DSEs.
Note: The data signaling rates are controlled by timing equipment within the network.
