Signal
Analogue
Assume infinite values in a range
The range is between the maximum value and the minor value
Consist in waves
Wave pattern
reflect the real world
Like microphone
Digital
The information consist in numbers
Digital signals are the result of converting analogue waves into numeric values
Rappresenting
Sound
Light
the analogue value is misured at specific intervall of time
Binary numbers
Consist in two digits
1 and 0
Use the number two as the base number for encoding end decoding the code
It's easy for electronic circuits use binary values
Because of 1 is "there is current", and 0 is "there is not current"
