Bit synchronous operation
Encyclopedia
Bit synchronous operation is a type of digital communication in which the data
circuit
terminating equipment (DCE
), data terminal equipment
(DTE
), and transmitting circuits are all operated in bit
synchronism
with a clock signal
.
In bit synchronous
operation, clock timing is usually delivered at twice the modulation rate, and one bit is transmitted or received during each clock cycle.
Bit synchronous operation is sometimes erroneously referred to as digital synchronization.
Data
The term data refers to qualitative or quantitative attributes of a variable or set of variables. Data are typically the results of measurements and can be the basis of graphs, images, or observations of a set of variables. Data are often viewed as the lowest level of abstraction from which...

Synchronous circuit
A synchronous circuit is a digital circuit in which the parts are synchronized by a clock signal.In an ideal synchronous circuit, every change in the logical levels of its storage components is simultaneous. These transitions follow the level change of a special signal called the clock...
