Bit-synchronous operation is a type of digital communication in which the

In the pursuit of knowledge, data (; ) is a collection of discrete values that convey information, describing quantity, quality, fact, statistics, other basic units of meaning, or simply sequences of symbols that may be further interpreted ...
circuit-terminating equipment (

clock signal
In electronics and especially synchronous digital circuits, a clock signal (historically also known as ''logic beat'') oscillates between a high and a low state and is used like a metronome to coordinate actions of digital circuits.

In bit-
synchronous operation, clock timing is usually delivered at twice the
modulation rate
In a digitally modulated signal or a line code, symbol rate, modulation rate or baud rate is the number of symbol changes, waveform changes, or signaling events across the transmission medium per unit of time. The symbol rate is measured in ''b ...
, and one bit is transmitted or received during each clock cycle.
Bit-synchronous operation is sometimes erroneously referred to as digital synchronization.
