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. Its input is a baseband signal, which is used to modulate a radio ...
A number of models of Sony 's PlayStation (PS) video game console were produced from 1994 to 2006. Most revisions of the PlayStation were made to fix known hardware issues or lower production costs and time, while others featured substantial external changes. Each region has its own model number; for example, Japan received the SCPH-1000, North ...
Frequency synthesizer. A frequency synthesizer is an electronic circuit that generates a range of frequencies from a single reference frequency. Frequency synthesizers are used in devices such as radio receivers, televisions, mobile telephones, radiotelephones, walkie-talkies, CB radios, cable television converter boxes, satellite receivers ...
The TI-99/4A is a self-contained console with the motherboard, ROM cartridge slot, and full-travel keyboard in the same case. The power supply is external. An RF modulator allows the use of a television as a monitor. Lowercase letters are displayed as small caps, rather than separate glyphs.
Atari 5200. The Atari 8-bit computers, formally launched as the Atari Home Computer System, [ 2 ] are a series of home computers introduced by Atari, Inc., in 1979 with the Atari 400 and Atari 800. [ 3 ] The architecture is designed around the 8-bit MOS Technology 6502 CPU and three custom coprocessors which provide support for sprites, smooth ...
The RF Switch/modulator is for older televisions predating composite audio/video ports. It is identical to and compatible with earlier Nintendo RF modulators. It has the Nintendo 64 RF modulator cased in GameCube packaging, and its RF switch is the same as the original Nintendo Entertainment System and Super NES.
An external RF modulator was necessary to use the computer with a TV set. The "20" in the computer's name was widely assumed to refer to the text width of the screen (although in fact, the VIC-20 has 22-column text, not 20) or that it referred to the combined size of the system ROMs (8 KB BASIC+8 KB KERNAL +4 KB character ROM).
Passband modulation. In electronics and telecommunications, modulation is the process of varying one or more properties of a periodic waveform, called the carrier signal, with a separate signal called the modulation signal that typically contains information to be transmitted. [1] For example, the modulation signal might be an audio signal ...
