Two systems exist for delivering television programming: the over-the-air television system, in which television signals are transmitted over the air by radio waves and received by a television antenna, and the cable television system, in which transmission occurs as radio frequency signals through coaxial cables or as light pulses through fiber-optic cables. TV channel frequencies in North America are different for over-the-air and cable television systems, but a channel of either system occupies a bandwidth of 6Mhz.
