: If analog can have a whole range of values as oposed to digital's two values,how come digital approach gives clearer,crispier etc output than analog ?
Ehmm ... well, a digital value isn't just 1 or 0, this is where all those bytes come in
Lets take a Volt-meter for example:
Say you want to measure a voltage between the 0 an 5V, on an analog volt-meter, you get numbers from 0 to 5 and a needle which points somewhere, between the, if you're lucky, you can get 1 decimal precision.
If you have a digital volt-meter, then the voltage is converted to a bitpatern (consisting of 1 or more bytes) which gives you a much higher accuracy. Taking 1 byte you can see the difference between 255 values in that 0 to 5 voltage-range, where as with the analog, you'll be lucky if you can get 50.
