Question

which of the following are true? (2 points) i. a high sampling rate must be used to create a high - quality digital file. ii. an analog sounds length determines the digital recordings size. iii. both digital pictures and recordings can be high - quality replications of the original analog data. i, ii, and iii ii and iii only i and ii only i and iii only

Explanation:

• I: A high - sampling rate generally leads to higher - quality digital files as it captures more details of the original signal.
• II: The size of a digital recording is determined by factors like sampling rate, bit - depth, and number of channels, not just the length of the analog sound.
• III: With proper encoding and high - quality conversion processes, digital pictures and recordings can be high - quality replicas of analog data.

Answer:

D. I and III only
