  • Analogue vs. Digital
    • Analogue
      • Have to amplified
      • Can pick up "noise" or interference
      • Hard to tell the real values of a noisy analogue signal
      • Amplitude and Frequency varies continuously
    • Digital
      • Binary (e.g 1 or 0)
      • Pulses of Energy
      • A digital receiver can decode this into it's original signal
      • Higher Quality because the information received is the same as the information transmitted - none of it has been corrupted
      • Transmit several signals at once
      • Easy to process by computers
      • Transferred in Bytes which is a lot higher quality and the amount of information stored is bigger as well
    • Info is converted into Electrical Signals before it's sent, it can be SUPERIMPOSED onto a CARRIER EM WAVE
      • Which is Analogue or Digital Waves
