What is true about the process of converting analog data into digital data?
a
To make the digital version be a more accurate representation of the analog data, the process should use fewer bits to represent each sample.
b
The digital version is a representation of the analog data but cannot include all of the details.
c
A longer interval between measured samples means more details will be captured in the conversion from analog to digital
d
The digital version contains all of the details of the analog data, as long as enough storage capacity is available.

b. The digital version is a representation of the analog data but cannot include all of the details.
Explanation:
Analog data are continuous infinite stream of data but since the computer has finite memory, these data could only be represented on the computer by converting them to finite data. This process is called analog to digital conversion.
The following are some of the things that should be noted when doing this conversion:
1. Since the digital version is a finite representation of the analog which is infinite, it (the digital version) cannot include all of the details in the analog.
2. For the digital version to be a more accurate version of the analog data it represents, as much bit as possible should be used to represent each sample.
3. Short intervals between measured samples means more details will be captured in the conversion from analog to digital.
