Digital Basics: 2. What is analogue? Analogue is the current broadcasting standard. It uses electrical signals (or radiowaves).
Terrestrial TV uses land-based transmitters to broadcast these signals which are then received by means of an aerial. Satellite beams the signals to a dish, while cable delivers much like a telephone line.
Digital technology makes better use of the available airwaves by squeezing a number of programmes into the same space currently occupying one. 8/15 Jobs at the BBC 696 Front page 100 News 101 Weather 400 TV listings 600
