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.

24V AC to DC Converter: Converting Alternating Current to Direct Current
A 24V AC to DC converter is a device that is used to convert alternating current (AC) to direct current (DC). This type of converter is commonly used in electronic devices and equipment that require a stable and consistent power supply. In this article, we will discuss the basic principles of AC to DC conversion, the different types of 24V AC to DC converters, and their applications. Principles of AC to DC Conversion AC power is supplied to most homes and buildings through the power grid. AC power changes direction and magnitude periodically, which means that the voltage level of the power supply may vary over time. In contrast, DC power flows in only one direction and maintains a constant...
