- The moon is said to be in quadrature at the first and last quarter, when her longitude differs 90° from that of the sun.
- Relation between two periodic functions when the phase difference between them is 90 degrees.

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).
