Digital signals don't vary, they have only got 2 values, on or off which makes them easier to process and read. They aren't as noisy as analogue signals- (sound is picked up from electrical interferences). You can send out more than one signal at once using only 1 cable. 1 of 2 Analogue Signals They vary continuously They aren't as good quality ad digital signals, there are more electrical interferences. 2 of 2
