/feɪz məˈdʒʊ.leɪ.tər/

Meaning and Usage

A phase modulator is a device used in communication systems that changes the phase of a carrier signal according to the modulating signal. It plays a crucial role in communication technologies, particularly in analog and digital transmission systems, allowing for the effective encoding of information.

• Frequency of Use: This term is primarily used in technical and academic contexts, particularly in engineering and communications studies. It is not commonly found in everyday conversation.
• Context of Use: More prevalent in written contexts, especially in technical papers, manuals, and scholarly articles, rather than in oral speech.

Example Sentences

1. The engineers designed a new phase modulator to improve the quality of the transmitted signals.

2. Инженеры разработали новый фазовый модулятор, чтобы улучшить качество передаваемых сигналов.

3. In modern communication systems, the phase modulator plays a vital role in signal processing.

4. В современных коммуникационных системах фазовый модулятор играет жизненно важную роль в обработке сигналов.

5. The performance of the phase modulator can significantly affect the overall system efficiency.

6. Эффективность фазового модулятора может существенно повлиять на общую эффективность системы.

Idiomatic Expressions

The term "phase modulator" is specific and technical, meaning it doesn't regularly appear in idiomatic expressions. However, below are some relevant technical expressions related to modulation in telecommunications:

1. Phase shift keying: This is a digital modulation scheme that conveys data by changes in the phase of a reference signal.

2. Фазовая угловая манипуляция используется для передачи данных, изменяя фазу опорного сигнала.

3. In phase: When two signals are aligned in phase, they reinforce each other, enhancing the signal quality.

4. Когда два сигнала находятся в фазе, они усиливают друг друга, улучшая качество сигнала.

5. Out of phase: This term describes two signals that are misaligned in phase and can cancel each other out.

6. Этот термин описывает два сигнала, которые не совпадают по фазе и могут подавлять друг друга.

7. Phase modulation index: This refers to the measure of the extent of phase modulation applied to the carrier signal.

8. Индекс фазовой модуляции – это мера степени фазовой модуляции, применяющейся к несущему сигналу.

Etymology

The term "phase" comes from the Greek word "phasis," meaning appearance or manner of presentation, while "modulator" is derived from the Latin "modulatus," which means to measure or moderate. "Modulate" relates to changing or adjusting, indicating the function of altering the phase of a signal.

Synonyms and Antonyms

• Synonyms: phase shifter, phase oscillator
• Antonyms: phase detector (used for identifying the phase differences, rather than modulating them)

In summary, the phrase "phase modulator" refers to an essential tool in telecommunications for altering signal phases, with its roots in Greek and Latin etymology reflecting its technical usage. The term thrives in written technical materials rather than in everyday speech.
