What does an RF modulator do?

An RF modulator converts baseband audio and video signals into radio frequency (RF) signals suitable for transmission over the airwaves or through coaxial cables. It modulates the input signals onto a specific carrier frequency, allowing them to be broadcasted or transmitted to TVs and other devices that can receive RF signals. This process enables the delivery of content over longer distances and through different types of media. RF modulators are commonly used in television broadcasting and in connecting devices like gaming consoles to older TVs.
