Polarization, английский
- Конструкция разъёма. в структурированных кабельных системах рекомендуется использование разъёмом, соответствующих стандарту we co. (western electric company). в отдельных случаях, когда необходимо обеспечить подключения телефонного оборудования к информац
- Поляризация
- A characteristic of the electric field on an electromagnetic wave in space. the directional aspects of a signal. signals can have circular or planar polarization. four types of polarization are used with satellites; horizontal, vertical, right-hand circular and left-hand circular. electromagnetic waves have the ability to vibrate in different radial directions. typically, satellite signal polarization is either horizontal or vertical. the signal coming from the satellite to the dish will either be vibrating along a horizontal or vertical plane. the receiving equipment must be adjusted to receive the correct polarization.
- Vibration of the electric field vector in specific direction perpendicular to the direction of propagation of the wave. also, restriction of the vibrations of the electromagnetic
- Alignment of the electric and magnetic fields that make up an electromagnetic wave; normally refers to the electric field. if all light waves have the same alignment, the light is polarized.
- When light penetrates certain crystals the emergent light is different than the entrance light. the emergent light emitted by the crystal vibrates in only one direction.
Modulation, английский
- Изменение характеристик несущей в соответствии с информативным сигналом
- Модуляция
- The process, or results of the process, whereby some characteristic of one signal is varied in accordance with another signal. the modulated signal is called the carrier. the carrier may be modulated in three fundamental ways: by varying the amplitude, called amplitude modulation; by varying the frequency, called frequency modulation; by varying the phase, called phase modulation.
- The process by which some characteristic (i.e., amplitude, phase) of one rf wave is
- The process by which some characteristic (i.e., amplitude, phase) of one rf wave is varied in accordance with another wave (message signal).
- The coding of information onto a carrier frequency. may use amplitude, frequency, phase, or time, plus many forms of on/off digital coding
- The ability to superimpose an external signal on the output beam of the laser as a control.
- The process by which the characteristic of one wave (the carrier) modifies another wave (the signal). examples include amplitude modulation (am), frequency modulation (fm), and pulse-coded modulation (pcm).
