An RF modulator (for radio frequency modulator) is a device that takes a baseband input signal and outputs a radio frequency-modulated signal. It has been suggested that this article or section be merged with Radio waves. ... For the musical use of modulation, see modulation (music). ... Baseband is an adjective that describes signals and systems whose range of frequencies is measured from 0 to a maximum bandwidth or highest signal frequency; it is sometimes used as a noun for a band of frequencies starting at 0. ...

In order to display picture information on a television, the data must be modulated, or conditioned, to the format that the television expects. This usually means combining the data with a carrier wave at a standardized frequency.

TV Modulators take the audio and video signal from a composite video, RGB, YUV or internal source, and generates a PAL or NTSC broadcast signal that can be fed into a television's aerial/coaxial connector. Composite video is the format of an analog television (picture only) signal before it is combined with a sound signal and modulated onto an RF carrier. ... The RGB color model utilizes the additive model in which red, green, and blue light are combined in various ways to create other colors. ... Example of U-V color plane, Y value = 0. ...

Internal RF Modulators are commonly found in VCRs, and older video game consoles such as the Atari 2600, NES, or Mega Drive. During the 1980s and early 90s, it was common for systems that did not have internal RF modulators to provide external units that connected to the antenna jacks of a television; however, as television designs gained composite, S-Video, and component video jacks, manufacturers stopped including the modulators as technology advanced. RF modulators are now largely a third-party product, purchased primarily to run newer equipment such as DVD players on old televisions. RF modulators produce a relatively poor picture, as image quality is lost during both the modulation from the source device, and demodulation in the television. However, the aerial connector is standard on all TV sets, even very old ones. As digital television becomes ubiquitous, the future of the RF modulator is grim. The video cassette recorder (or VCR, less popularly video tape recorder) is a type of video tape recorder that uses removable cassettes containing magnetic tape to record audio and video from a television broadcast so it can be played back later. ...

Multi Channel Video Modulators

Multi Channel RF Modulators are commonly used in home audio/video distribution. These devices have multiple audio and video inputs and one RF output. Audio/Video outputs from source devices such as a DVD player, VCR, or DSS receiver are connected to the Audio/Video inputs on the modulator. The modulator is then programmed to broadcast the signals on a certain frequency. That RF broadcast is then received by the connected TV. When the TV is tuned to the programmed channel, the audio/video signal of the source device is accessed. RF modulation can become difficult in a CATV system. High pass, low pass, and notch filters must be used to block certain frequencies, or channels, so that the modulator can broadcast the audio/video signal of the source device on that channel.

Audio Modulators

Different RF modulators that are audio only, and output on FM Radio frequencies are also used in car audio to connect such devices as add-on CD changers and video systems. These FM modulators also suffer from loss of quality and interference issues. The abbreviations FM, Fm, and fm may refer to: Electrical engineering Frequency modulation (FM) and its most common applications: FM broadcasting, used primarily to broadcast music and speech at VHF frequencies FM synthesis, a sound-generation technique popularized by early digital synthesizers Science Femtometre (fm), an SI measure of length...
