In digital electronics, a synchronous circuit is a digital circuit in which the changes in the state of memory elements are synchronized by a clock signal. In a sequential digital logic circuit, data is stored in memory devices called flip-flops or latches. The output of a flip-flop is constant until a pulse is applied to its "clock" input ...
In electrical engineering terms, for digital logic and data transfer, a synchronous circuit requires a clock signal.A clock signal simply signals the start or end of some time period, often measured in microseconds or nanoseconds, that has an arbitrary relationship to any other system of measurement of the passage of minutes, hours, and days.
Synchronous and asynchronous transmissions are two different methods of transmission synchronization. Synchronous transmissions are synchronized by an external clock, while asynchronous transmissions are synchronized by special signals along the transmission medium.
In event driven architectures, synchronous transactions can be achieved through using request-response paradigm and it can be implemented in two ways: [16] Creating two separate queues: one for requests and the other for replies. The event producer must wait until it receives the response. Creating one dedicated ephemeral queue for each request.
Synchronous serial communication describes a serial communication protocol in which "data is sent in a continuous stream at constant rate." [1]Synchronous communication requires that the clocks in the transmitting and receiving devices are synchronized – running at the same rate – so the receiver can sample the signal at the same time intervals used by the transmitter.
Synchronous speeds for synchronous motors and alternators depend on the number of poles on the machine and the frequency of the supply. The relationship between the supply frequency, f, the number of poles, p, and the synchronous speed (speed of rotating field), n s is given by: = .
A synchronous electric motor is an AC electric motor in which, at steady state, [1] the rotation of the shaft is synchronized with the frequency of the supply current
Clock synchronization is a topic in computer science and engineering that aims to coordinate otherwise independent clocks.Even when initially set accurately, real clocks will differ after some amount of time due to clock drift, caused by clocks counting time at slightly different rates.
