why choose digital over analogue?
both signals pick up random noise; both signals weaken and reduce the quality of the sound
analogue signals become weaker as they travel- needs to be amplified at selected intervals
digital signals can travel long distances at higher quality
no need to tine digital tv because the reception does not need to be a certain frequency
digital signals have no variation in frequency or amplitude
analogue signals have many different values
when analogue signals become weaker, the quality of the signal gets worse- it is hard to distinguish between noise and original sound
if digital sounds weaken, the quality is maintained because the pulses can be recognised as being 1 or 0- therefore, any interference can be removed
noise is easily removed form a digital sound
more information can be sent at one time with a digital signal
