What is RF (Radio Frequency)?

RF (Radio Frequency)
RF signals are very common in our world, from radio and TV broadcasts to lighting control systems and garage door openers! In all cases radio frequency delivery is utilized whenever signals must travel through the airwaves. Because of the omni-directional nature of RF signals they are useful in home theater remote control systems and centrally-located DSS receivers. You will also find RF input connections on TVs VCRs and DSS receivers. Special RF connections may also be found on laser disc players. These RF connections allow interface with an outboard RF demodulator that is required to derive the Dolby Digital audio tracks from certain laser discs.
