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 frequency source.^[1]

RF modulators operate on different channels depending on the region and have been integrated into various home electronics. However, they tend to produce lower image quality than a baseband connection due to losses during the modulation and demodulation process. In professional broadcast settings, more sophisticated modulators are used.
