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.

NETWORK AND TRANSMISSION LINES 100 MCQ WWW.ALLEXAMREVIEW.COM.pdf

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.

To measure the characteristic impedance of transmission lines using frequency domain method and to differentiate between the matched and unmatched lines.

 Подождите, - сказала Соши.  - Сейчас найду. Вот. Все прочитали: - Разница в весе незначительна… разделяются вследствие газовой диффузии… 10,032498X10134 в сравнении с 1939484X1023. - Ну вот, наконец-то! - вскрикнул Джабба.

Он набрал в легкие воздуха. - Вы хотите приделать к Цифровой крепости черный ход.

Я просто подумал… - Толстяк быстро убрал бумажник.  - Я… я… - Совсем растерявшись, он сел на край постели и сжал руки. Кровать застонала под его весом.  - Простите. Беккер вытащил из вазы, стоявшей на столике в центре комнаты, розу и небрежно поднес ее к носу, потом резко повернулся к немцу, выпустив розу из рук.

Беккер заговорил по-испански с сильным франко-американским акцентом: - Меня зовут Дэвид Беккер. Я из канадского посольства. Наш гражданин был сегодня доставлен в вашу больницу.

 - Главный бастион, два набора пакетных фильтров для Протокола передачи файлов, Х-одиннадцать, туннельный блок и, наконец, окно авторизации справа от проекта Трюфель. Внешний щит, исчезающий на наших глазах, - открытый главный компьютер. Этот щит практически взломан.

 - Посылает сообщение о том, что Танкадо ликвидирован. Сьюзан повернулась к Беккеру и усмехнулась: - Похоже, у этого Халохота дурная привычка сообщать об убийстве, когда жертва еще дышит. Камера последовала за Халохотом, двинувшимся в направлении жертвы.
