  • Căn bản về TCP/IP TCP/IP (Transmission Control Protocol/Internet Protocol) là một bộ protocols (giao thức) được thiết kế để đạt hai mục tiêu chính: 1. Cho phép truyền thông qua các đuờng dây của mạng rộng (Wide Area Network - WAN). 2. Cho phép truyền thông giữa các môi trường đa dạng. Do đó hiểu được cái gốc của các protocols nầy giúp ta hiểu đuộc sự quan trọng của chúng trong các mạng ngày nay.

  • • Analog voice data must be translated into a series of binary digits before they can be transmitted in digital transmission system. One means of doing this is called pulse amplitude modulation (PAM). • The process of converting analog signal to digital is also known as A_to_D conversion or A/D conversion. The circuit does the conversion known as A/D converter. In analog modulation (continuous wave modulation), some parameter of a sinusoidal carrier wave is varied continuously in accordance with the message signal. ...

  • Transmission electron microscopy (TEM) is a technique where the electron-beam is transmitted through an ultra-thin specimen, interacting with specimen as it passes through it. An image is formed from the interaction of the electrons transmitted through the specimen, which is then magnified and focused onto an imaging device, such as a fluorescent screen, a photographic film, or a charge-coupled device (CCD) sensor. This technique is capable of imaging at significantly high resolution than the light microscopes, owing to the small de-Broglie wavelength of electrons....

  • This book analyses the key issues of the offshore wind farm's energy transmission and grid integration infrastructure. But, for this purpose, there are not evaluated all the electric configurations. In the present book is deeply evaluated a representative case. This representative case is built starting from three generic characteristics of an offshore wind farm: the rated power, the distance to shore and the average wind speed of the location.

  • Transmission: the propagation of a signal, message, or other form of intelligence by any means such as optical fiber, wire, or visual means. Switching: selects the route to the desired destination that the transmitted signal travels by the closing of switches in either the space domain or the time domain or some combinations of the two.

  •  This guide publication is a reference containing fundamental engineering guidelines and basic recommendations on structural and electrical aspects of transmission line design, as well as explanations and illustrations. The many cross-references and examples should be of great benefit to engineers performing design work for RUS borrower transmission lines. The guide should be particularly helpful to relatively inexperienced engineers beginning their careers in transmission line design.

  • There are many occasions when data need to be transmitted over a voice communication network. Many people use a computer to connect to their Internet Service Provider via the telephone lines to transmit and receive data, check their email, surf the Web, etc. Telephone networks were originally built for human speech, not for computer data and is unsuitable for digital communication in its raw form.
