Transmission line

In electrical engineering , a transmission line is a specialized cable or other structure designed to conduct electromagnetic waves in a contained manner. The term applies when the conductors are long enough that the wave nature of the transmission must be taken into account. This applies especially to radio-frequency engineering because the short wavelengths mean that wave phenomena arise over very short distances this can be as short as millimetres depending on frequency. However, the theory of transmission lines was historically developed to explain phenomena on very long telegraph lines, especially submarine telegraph cables. Transmission lines are used for purposes such as connecting radio transmitters and receivers with their antennas they are then called feed lines or feeders , distributing cable television signals, trunklines routing calls between telephone switching centres, computer network connections and high speed computer data buses. RF engineers commonly use short pieces of transmission line, usually in the form of printed planar transmission lines , arranged in certain patterns to build circuits such as filters.

Communication network and transmission pdf In a telecommunications network, one begins at the terminal site at the. Transmission is about communication, and people have communicated for a long time. Fiber optic data transmission systems send information over fiber by turning. The diagram. Communication networks based on serial data transmission are the plat. Communication networks provide a number of advantages over sy- stems in which a.

Energy can be transmitted either by the radiation of free electromagnetic waves as in the radio or it can be constrained to move or carried in various conductor arrangement known as transmission line. Thus a transmission line is conductive method of guiding electrical energy from one place to another. In communications, these lines are used as a link between an antenna and transmitter or a receiver. Transmission lines are employed, not only to transmit energy, but also as circuit elements like inductor, capacitors, resonant circuits, filters, transformers and even inductors at very high frequencies. Knowledge of the values of electrical circuit parameters associated with the transmission line is necessary to understanding and design. If a long line consisting of two parallel uniform conductors is carrying current, there is a magnetic field around conductors and voltage drop along them.

Джабба посмотрел на ВР. - Около двадцати минут. Их надо использовать с толком. Фонтейн долго молчал. Потом, тяжело вздохнув, скомандовал: - Хорошо.

Но как только шифр будет взломан… - Коммандер, а не лучше ли будет… - Мне нужен ключ! - отрезал. Сьюзан должна была признать, что, услышав о Цифровой крепости, она как ученый испытала определенный интерес, желание установить, как Танкадо удалось создать такую программу. Само ее существование противоречило основным правилам криптографии. Она посмотрела на шефа.

 - И откуда мы знаем, что именно ищем.

Человек смерил его сердитым взглядом: - Pues sientate. Тогда сядьте. Вокруг послышалось шушуканье, старик замолчал и снова стал смотреть прямо перед. Беккер прикрыл глаза и сжался, раздумывая, сколько времени продлится служба. Выросший в протестантской семье, он всегда считал, что католики ужасно медлительны. Теперь он молил Бога, чтобы священник не торопился, ведь как только служба закончится, он будет вынужден встать, хотя бы для того чтобы пропустить соседей по скамье.

Я ничего не нашел на Северную Дакоту, поэтому изменил направление поиска. В записи, которую я обнаружил, фигурирует другое имя - N DAKOTA. Сьюзан покачала головой. - Такие перестановки - стандартный прием. Танкадо знал, что вы испробуете различные варианты, пока не наткнетесь на что-нибудь подходящее. NDAKOTA - слишком простое изменение.

 Мой человек отнимет. - И что .

Я требую выпустить меня отсюда. В ответ - тишина. Его руки крепче сжали ее шею. - Я сейчас ее убью. Сзади щелкнул взведенный курок беретты.
