Modulator, английский
- Demodulator unit
- Модулятор
- A device which converts the video signal and audio signal onto a viewable tv channel. it takes the video and audio signals that are separated by the receiver and combines them into a signal that can be received by an ordinary tv set. this signal is called an rf signal, meaning radio frequency, and is usually set for either channel 3 or 4. the advantage of using a modulator is that it permits the use of standard tv receivers for displays, but the signal quality is not as good as using a direct video and audio feed to a monitor tv display. as with receivers, modulators should also be redundant. glossary/56
- A device that imposes a signal on a carrier.
Modulator valve, английский
Valve within an automatic transmission that responds to changes usually in manifold depression via a vacuum modulator, and driveshaft rotational speed, to provide a signal in the form of hydrauhc pressure or torque which actuates a boost valve in the pressure regulator to modify l
