- 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
- Analogue
