There are two different possible way to set up synchronization for a synchronous transmission. First way is set up a separate clock line between transmitters and receiver but this only works for short range transmission since in long range transmissions the clock pulses can receive timing errors. The better choice for long distance is to embed the clocking information in the data signal. You can do this with Manchester or differential Manchester encoding for digital signals.

What transmission synchronization methods uses the cyclic redundancy check method for error checking?
Synchronous
What the different between synchronous and asynchronous?
In asynchronous transmission , the receiver and the transmitter each use their own clock signals so its not possible to know when a word starts and stops. while in synchronous , the receiver and the transmission have common clock signals.
Difference between synchronous and Asynchronous serial communication in micro controller?
Synchronous: The synchronous format, receiver or transmitters are synchronized. A block of information is transmitted along with the synchronization information. This is clk oriented transmission format. This information is specially used for high speed transmission. Usually in this synchronous system one or two SYNC character are used for data synchronous data system. Transmission device send data continuously to receiving device. If the data is not ready this system continuously synchronous data until the data is unviable. Asynchronous: It is character oriented. Each character comes with the information of start and stop. In this system 1 for mark, 0 for space. When data are being transmitted a receiver stay at high at logic 1. This is specially used in low speed transmission.
Which type of digital transmission should you use?
synchronous serial transmission
What is syncronous modem?
Synchronous and Asynchronous data transfer are two methods of sending data over a phone line. In synchronous data transmission, data is sent via a bit-stream, which sends a group of characters in a single stream In order to do this, modems gather groups of characters into a buffer, where they are prepared to be sent as such a stream. In order for the stream to be sent, synchronous modems must be in perfect synchronization with each other. They accomplish this by sending special characters, called synchronization, or syn, characters. When the clocks of each modem are in synchronization, the data stream is sent. In asynchronous transmission, data is coded into a series of pulses, including a start bit and a stop bit. A start bit is sent by the sending modem to inform the receiving modem that a character is to be sent. The character is then sent, followed by a stop bit designating that the transfer of that bit is complete.
In advance operating system what is process synchronization?
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. There are many types of synchronization: * barrier * lock/semaphore * non-blocking synchronization * synchronous communication operations advantages of synchronous communications are * no need of start and stop bits * higher data rates possible * the actual data length need not be fixed
What is the meaning of synchronization?
The act of synchronizing; concurrence of events in respect to time.
What is a synchronizer?
Synchronous motors are those that run only at Synchronous speed ie.. constant speed.
What is synchronous networking?
Synchronous networking refers to a communication method where data is transmitted at regular, predictable intervals, typically synchronized with a clock signal. This ensures that both the sender and receiver are aligned in timing, allowing for efficient and reliable data transfer. Common applications include telephony and certain types of digital communication systems. By maintaining synchronization, it minimizes latency and errors in data transmission.
What is the basic block diagram of a synchronous frame?
A basic block diagram of a synchronous frame typically includes several key components: a data source that generates the information to be transmitted, a synchronous transmitter that encodes this data along with a clock signal for synchronization, and a communication medium (like a cable or wireless channel) that carries the signal. On the receiving end, a synchronous receiver decodes the received signal using the clock signal to accurately extract the data. Additionally, there may be error detection and correction blocks to ensure data integrity during transmission.
What transmission is data sent in a constant stream of frames?
synchronous transmission. In a asynchronous transmission, data is sent as individual data bytes
Need what synchronous pulse in time division multiplexing?
In time division multiplexing (TDM), a synchronous pulse is essential for coordinating the timing of data transmission from multiple sources over a shared communication channel. This pulse ensures that each data stream is allocated a specific time slot in a repeating cycle, allowing for orderly and efficient transmission without overlap. By synchronizing the timing of data packets, the system can accurately reconstruct the original signals at the receiving end. This synchronization is crucial for maintaining data integrity and minimizing errors in communication.
