Key technologies of modern communication
Digital communication technology: Digital communication transmission of digital signal communication, is through the analog signal from the source through digital terminal source coding become digital signal, the digital signal from the terminal with channels in the channel coding into suitable for digital signal, and then by the modem modulation signal to the system using the digital channel, eventually transferred to obtaining-information after instead of transformation, and time according to the direction of information transmission, data communication system with simplex method, half duplex mode and three full operating mode.
Program-controlled exchange technology: Program-controlled exchange technology refers to the exchange of various kinds of communication in which people use specialized computers to transfer preprogrammed programs to computers. With program-controlled exchange technology developed digital switches processing speed, small size, large capacity, strong flexibility, service function, easy to change the switch function, is advantageous for the construction of intelligent network, to provide customers with more and more convenient telephone service, also can realize the fax, data, image communication exchange, it is controlled by program, is carried out by time division multiplexing network physical circuit switching a telephone exchange equipment.

Connection technology: The access network technology is one of the core parts of the modern telecommunication network system, which has the function of connecting local end users and end users. The wire network structure is mainly composed of UNI (user network interface) and SNI (business node interface). The core network is the link connecting user network interface and business node interface. Access network’s main function is to realize the user and the terminal equipment effective communication and information connection, compared with the optical fiber communication technology and bluetooth technology, access network technology does not have the reuse and cross connection.
Bluetooth technology: With the increasing intelligence of mobile phones, bluetooth technology has gradually entered people’s life. Bluetooth is arguably the latest communication technology in all communications technologies. Currently, mobile phones, laptops, wireless headphones and many other peripherals have bluetooth capabilities. It can be said that the promotion of bluetooth technology greatly simplifies the communication between the terminal devices. Bluetooth technology can achieve communication between wireless devices and the Internet, and the advantages of bluetooth technology to another big reflected in the exchange of information users in the use of bluetooth technology in the process of don’t need to pay fees.

Generating Direct Current: The AC-DC Converter
Direct current (DC) is a type of electrical current that flows in only one direction. It is widely used in electronics, power supplies, and many other applications. However, most of our electrical power grid is alternating current (AC), which means that the electrical current periodically changes direction. Therefore, to use AC power in DC devices, we need an AC-DC converter to convert the AC power into DC power. In this article, we will discuss how an AC-DC converter works. Firstly, let understand the difference between AC and DC power. AC power alternates between positive and negative voltage cycles, and it flows in a sine wave pattern. On the other hand, DC power flows in a straight line, and it has...
