noun a device or substance that modulates, or regulates, a signal or process
In optics, a modulator is used to control the intensity, phase, or polarization of light for various applications such as telecommunications or laser technology.
In electronics, a modulator is used to vary a property of a high-frequency periodic waveform, such as its amplitude, frequency, or phase.
In telecommunications, a modulator is used to encode information onto a carrier signal for transmission.
In acoustics, a modulator is used to vary the parameters of a sound wave to create effects such as tremolo or vibrato in music.
In medical imaging, a modulator is used to control the intensity of a radiation beam to produce images of the internal structures of the body.
In the field of telecommunications, a modulator is used to convert digital data into analog signals for transmission over radio waves. Writers may research and explain this process in articles or technical documentation.
Psychologists may use modulators in the context of biofeedback therapy, where devices modulate physiological signals to provide feedback to patients. This can help patients learn to control their bodily responses.
Engineers working in fields such as audio engineering or telecommunications use modulators to manipulate signals for various purposes, such as modulation of sound waves or data transmission.
Musicians may use modulators in electronic music production to create new sounds and effects by modulating audio signals. This can add depth and complexity to musical compositions.
