What is the meaning of synchronisation?

Answer 1

The obtaining of a desired fixed relationship among corresponding significant instants of two or more signals.Or A state of simultaneous occurrences of significant instants among two or more signals.

Answer 2

Synchronisation (of Greek sýn, "together" and chrónos, "time", literally about "manufacturing synchronisation"), equivalently also synchronization, designates the temporal one on the other co-ordinating of procedures. Synchronisation ensures thus for the fact that actions in a certain order arise at the same time and/or.

In different fields of knowledge the term synchronisation is used frequently in closer meanings:

Generators in a.c. mains must work with the same frequency and phase position. For the determination of the synchronous condition the synchronoscope is used. For a synchronous enterprise it is also important that all power stations working in the group are regulated in the same procedure.

Synchronisation designates the " contemporaneous" running off of picture and clay/tone with the film (see to synchronisation (film)). Generally the Nachvertonen is called of films synchronizing. In Germany "non-German-language" films are synchronized for the 1930er years.
In digital technique synchronisation means that two devices (z. B. transmitters and receivers) are synchronized, if both work with a clock frequency, which is alike within defined tolerances. The signals of synchronized devices have a firm phase relationship to each other. The procedure, for which the German technical term reciprocal laying is usually used, is called also as synchronization or following English technical term synchronisation.

Answer 3

Synchronization or Synchronizing in the Electrical Power industry is as follows.
Before an incoming alternator can be connected to the power grid it must be adjusted so that its incoming circuit breaker can be closed onto the system without damaging the alternator.
To synchronize the incoming alternator to the system it has to be adjusted so that the following parameters are all equal and identical.
1. Incoming volts from the machine adjusted to the running volts of the system.
2. Incoming speed (frequency) adjusted so that the two systems are identical.
Generally the alternator circuit breaker is closed when the two speeds are matched on a synchroscope. A synchroscope is a meter with a rotating pointer (similar to a clock). If the incoming alternator speed is less than the system speed (frequency) the needle rotates anti-clockwise and conversly if it is faster it rotates clockwise. The circuit breaker can only be closed when the speed/volts are identical and are at the 12 O'clock position. Generally there is a Synch Check Relay in the circuit breaker closing circuit to only allow the circuit breaker to close when the conditions are exactly in synchronization.

Answer 4

I give you an example.
I had 2 Gen sets which were of different types and If I had to use both to get full power I had to synchronise both.
This was done by the Vendor of Gen sets.
One only could be used at a time to click my load and this would noy take my load.
You got it ?.

Answer 5

Synchronization is a problem in timekeeping which requires the coordination of events to operate a system in unison. The familiar conductor of an orchestra serves to keep the orchestra in time. Systems operating with all their parts in synchrony are said to be synchronous or in sync. Some systems may be only approximately synchronized, or plesiochronous. For some applications relative offsets between events need to be determined, for others only the order of the event is important.

Answer 6

The best way to explain synchronisation is....Think of a dancing..preformed by a group.....Every body in the group should dance a step correctly, timingly and more important without any fault...

Answer 7

synchronisation
n 1: the relation that exists when things occur at the same time;
"the drug produces an increased synchrony of the brain
waves" [syn: synchronism, synchrony, synchronicity,
synchroneity, synchronization, synchronizing]
[ant: asynchronism, asynchronism, asynchronism]
2: an adjustment that causes something to occur or recur in
unison [syn: synchronization, synchronizing, synchronising]
3: coordinating by causing to indicate the same time; "the
synchronization of their watches was an important
preliminary" [syn: synchronization, synchronizing]

Answer 8

- syn·chro·niz·er noun

Answer 9

If you want a machine synchronized (my man can explain this so much better then I he does this everyday) You have to adjust the two to work at the same speed, same motion. There synchronized.

Answer 10

Synchronization is a problem in timekeeping which requires the coordination of events to operate a system in unison. The familiar conductor of an orchestra serves to keep the orchestra in time. Systems operating with all their parts in synchrony are said to be synchronous or in sync. Some systems may be only approximately synchronized, or plesiochronous. For some applications relative offsets between events need to be determined, for others only the order of the event is important.

Today, synchronization can occur on a global basis due to GPS-enabled timekeeping systems.

Transport
Synchronization was not a rigorous requirement in transportation until the nineteenth century, when railroad transportation had to share railroad track. Thus strict timekeeping was a safety requirement. To this day, railroads can communicate and signal along their tracks, independently of other systems for safety.

Communication
The lessons of timekeeping are part of engineering technology. In electrical engineering terms, for digital logic and data transfer, a synchronous object requires a clock signal.

Timekeeping technologies such as the GPS satellites and Network time protocol (NTP) provide real-time access to a close approximation to the UTC timescale, and are used for many terrestrial synchronization applications.

Synchronization is an important concept in the following fields:
* Computer science "In computer science, especially parallel computing, synchronization means the coordination of simultaneous threads or processes to complete a task in order to get correct runtime order and avoid unexpected race conditions."
* Physics The idea of simultaneity has many difficulties, both in practice and theory.
* Telecommunication
* Cryptography
* Multimedia
* Photography
* Music (rhythm)
* Synthesizers

Synchronization has several subtly distinct sub-concepts:
* Rate synchronization
* Phase synchronization
* Time offset synchronization
* Time order synchronization

Some uses of synchronization
Whilst well-designed time synchronization is an important tool for creating reliable systems, excessive use of synchronization where it is not necessary can make systems less fault-tolerant, and hence less reliable.

* Synchronization of image and sound in sound film.
* Synchronization is important in fields such as digital telephony, video and digital audio where streams of sampled data are manipulated.
* Arbiters are needed in digital electronic systems such as microprocessors to deal with asynchronous inputs. There are also electronic digital circuits called synchronizers that attempt to perform arbitration in one clock cycle. Synchronizers, unlike arbiters, are prone to failure. (See metastability in electronics).
* Encryption systems usually require some synchronization mechanism to ensure that the receiving cipher is decoding the right bits at the right time.
* Automotive transmissions contain synchronizers which allow the toothed rotating parts (gears and splined shaft) to be brought to the same rotational velocity before engaging the teeth.
* Synchronization is also important in industrial automation applications.
* Time codes are often used as a means of synchronization in film, video, and audio applications.
* Flash photography, see Flash synchronization
* File synchronization is used to maintain the same version of files on multiple computing devices. For example, an address book on a telephone might need to by synchronized with an address book on a computer.
* Software applications must occasionally incorporate application-specific data synchronization in order to mirror changes over time among multiple data sources at a level more granular than File synchronization. An example use of this is the Data Synchronization specification of the Open Mobile Alliance, which continues the work previously done by the SyncML initiative. SyncML was initially proposed to synchronize changes in personal address book and calendar information from computers to mobile phones, but has subsequently been used in applications that synchronize other types of data changes among multiple sources, such as project status changes.
* Video or audio synchronization of media data that stored on different computers via a network like the software syncMaker PRO [1] does.
* Code synchronization
