  2. Video modulation - Wikipedia

    en.wikipedia.org/wiki/Video_modulation

    The types of video modulation can be classified by the way that a carrier wave is combined with video signal. The video signal and carrier wave both exist in waveform and when the carrier wave "carries" the video signal, the shape of carrier wave is changed and the changed carrier wave is the RF signal.

  3. RF modulator - Wikipedia

    en.wikipedia.org/wiki/RF_modulator

    An RF modulator (radio frequency modulator) is an electronic device used to convert signals from devices such as media players, VCRs and game consoles to a format that can be handled by a device designed to receive a modulated RF input, such as a radio or television receiver.

  7. Radio over fiber - Wikipedia

    en.wikipedia.org/wiki/Radio_over_fiber

    Radio over fiber (RoF) or RF over fiber (RFoF) refers to a technology whereby light is modulated by a radio frequency signal and transmitted over an optical fiber link. Main technical advantages of using fiber optical links are lower transmission losses and reduced sensitivity to noise and electromagnetic interference compared to all-electrical signal transmission.
