Rf channel frequency chart
How are TV channels assigned frequencies?
TV channel frequencies are assigned in 54 to 806 MHz RF frequency band. These total spectrum is divided into 68 TV channels. Each channel occupies 6MHz bandwidth. To calculate picture carrier value, add 1.25MHz to the lower frequency range. To derive sound carrier value, add 4.5 MHz to the picture carrier obtained.
How are high frequency signals transmitted over cable TV?
In order to transmit these high frequency signals over cable they are downconverted to lower frequencies using mixers. Few of these channels are mapped to standard 6MHz TV channel frequencies. The cable TV channel frequencies are nonbroadcast channels. Heterodyne processors are employed to translate received signals to the desired channels.

WHAT’S A SPECTROGRAM DISPLAY? Additional Information: While it’s very important to determine frequency, occupied bandwidth and relative signal strength; we also need to find out how often a signal is on. The spectrogram display is the one of the best ways for us to measure this aspect of a signal.
