Can any analog signal be converted to digital?

Answer 1

yes of course we can convert an analog signal to digital...

the device which converts analog to digital is called ADC{ANALOD TO DIGITAL CONVERTER}..

AND IT USES A VERY SIMPLE TECHNIQUE

i will tell you how.

let us suppose we are having any analog signal,

so we find the maximum amplitude of that signal by looking at the curve.

then we find the minimum amplitude of that signal.

thus we are now having the full range of the signal between which its value remains..

now let the maximum value is 5 volts and minimum is 0 volts.

so what we do now is that we take any reference point between 0 and 5 volt

let us split 0 -5 volt in two groups

1)0 to 2.5 volt and

2)2.5 to 5 volt

now by the help of programming we set 0 to 2.5 volt as zero and 2.5 votl to 5 volt as 1

so what ever value which will lie between 0 and 0.5 will be converted to 0 and the values between 2.5 and 5 will be converted to 1.

thus we get a digital signal from an analog signal
