What is frequency range of television?

Answer 1

Broadcast TV in the US occupies selected frequency bands between 54 and 698 MHz. It used to go all the way up to 896 MHz, but the frequencies formerly used for channels 52-83 have been reassigned to other purposes.

Each individual TV channel occupies a band of about 6 MHz.

If you're happier expressing frequencies in meters (of wavelength), this corresponds to from about 5.5 meters to around 0.5 meters. There are some pretty big gaps in there, though; TV doesn't use every frequency in that range (among other things, FM radio takes a chunk of it).

Answer 2

Most televisions will handle a full audio range from 20Hz to 18Khz depending on the quality of the audio received. However, speakers in televisions are normally not capable of delivering a full bandwidth output. In most cases, using external speakers will offer an improved low and high frequency response. Some televisions feature speaker outputs to drive speakers directly while others have a line output or headphone output that can be taken into an amplifier. If sound quality is important, try external speakers and see how much better it can sound.
