The electronic equipment required to combine video and audio signals from a studio and convert them to radio frequencies (r-f) for distribution on a cable system Also, a very low-powered television signal generator used to provide signals for distribution on a CATV system
A simulated drug or electrolyte, for which an instantaneous preparation-wide serum level may be specified by the user At any particular serum level, a Modulator may influence the behavior of the preparation in one or more of a fixed set of Modulator Effect Modalities
A device which superimposes the amplitude, frequency or phase of a wave or signal onto another wave or signal (a carrier), which is then used to convey the original signal via a transmission medium (e g satellite link)
The electronic device in a modem that encodes data for transmission See demodulator
In FM synthesis and elsewhere, a modulator that is used to modify the output of another operator, creating rich complex tones This process is known as modulation
In wireless microphones, an electronic circuit to superimpose an audio signal on a RF signal, usually by varying its frequency in synchronization with the audio signal Also called an FM modulator
Equipment that converts audio, video, or data signals (baseband) into an RF signal
(Video/Audio) An electronic signal processor that combines a video/audio signal with a carrier signal for distribution A later demodulator removes the carrier following transmission to restore the original signal Analogous to radio transmission
