Let us consider the principle of data transmission over digital communication channels using the example of the PCM-30 system. The transmission medium in PCM systems is a digital linear path (LT), the structure of which is shown in Fig. 3.49. It includes transmitting and receiving terminal equipment
A communication line generally consists of a physical medium through which electrical information signals, data transmission equipment and intermediate equipment are transmitted. A synonym for the term communication line is the term communication channel. Physi
Human life in the twenty-first century is directly related to artificial intelligence. Knowledge of the main milestones in the creation of computers is an indicator of an educated person. The development of computers is usually divided into 5 stages - it is customary to talk about five generations. 1946
One of the first devices (V-IV centuries BC), from which the history of the development of computers can be considered to have begun, was a special board, later called the “abacus”. Calculations on it were carried out by moving bones or stones in the recesses of bronze boards
Information transfer is a term that combines many physical processes of moving information in space. Any of these processes involves components such as a source and receiver of data, a physical carrier of information and a channel (medium) for its transmission.
In modern society, it is difficult to imagine life without such a unique thing as a computer. Models and types of modern computers surprise us with their capabilities, compact dimensions, design... But the first computers were not like that at all
Control Communication, communications, radio electronics and digital devices Communication channel is a system of technical means and signal propagation medium for transmitting messages (not only data) from a source to a recipient (and vice versa). Communication channel, understood in
How can you live without computers, smartphones and other gadgets today? It's even harder to realize that 50 years ago these technologies could only be learned from science fiction books. We offer a short excursion into history to find out how the person developed
In order to transmit various information, a medium for its distribution must initially be created, which is a set of lines or data transmission channels with specialized receiving and transmitting equipment. Lines, or kan
They appeared after the Second World War, when the discoveries of mathematicians and other scientists made it possible to implement a new way of reading information. And although today these machines seem like outlandish artifacts, they became the progenitors of modern, familiar
