Reasons to digitally approximate analog signals DO NOT include: (a) having digit

Question

Reasons to digitally approximate analog signals DO NOT include:

(a) having digitalized sampled data allows saving of data to computer hardware such as disks.

(b) digital always requires less hardware than analog circuitry.

(c) having a stream of sampled data allows applying well known mathmatical formulas that can be updated as required.

(d) By sampling analog periodically in time and quantizing amplitude into digital representations, the signal can be manipulated in computer hardware and software.

Please let me know which one of these is the correct answer. Thanks in advance.

Explanation / Answer

(c) having a stream of sampled data allows applying well known mathmatical formulas that can be updated as required.
