### Analogue / Digital Communications
|
|
|
|
#### Summary
|
|
|
|
Analogue and digital communications are not fundamentally different. They use the same transmission system ( copper / fibre optic cabling / EM waves ); in the 5-stage model, the only difference is the "transmitter" and "receiver".

|
Digital communications allow us to send data without errors, but are limited to a binary value, which can be interpreted by the receiver to reconstruct the initial data.
