3.24 Advantages of Digital signals

Describe the advantages of using digital signals rather than analogue signals.

When a signal is transmitted from one place to another it gains noise, noise is where the signal becomes distorted during transmission. In analogue signals distorted signals can not be regenerated into their original form because it is impossible to calculate what it originally looked like. But because digital signals only have a value of 1 or 0 if they were distorted it is quite obvious as to there previous value... as shown in the below diagram.
