Entries found for search: radio frequency

radio frequency (RF) : An alternating AC current or voltage having a frequency above about 100kHz, so-called because these frequencies are radiated as electro-magnetic waves by radio and television, and as high as 30 GHz (30,000 MHz). The constant frequency of the carrier wave (the frequency which you tune into) falls within this range. This is then modulated by the audio (or other) signal, according to some process such as AM or FM.
