Step-by-Step Solution
Solution:
Step 1: Understand transmission needs for voice over internet
Internet communication requires signals that are clear and less prone to errors, which digital signals provide by using discrete values.Step 2: Choose the best signal type for clarity and reliability
Digital signals convert voice into 0s and 1s, making transmission more accurate and less affected by noise compared to analog signals.Final Answer:
Digital signal, because it uses discrete values for accuracy -> Option AQuick Check:
Voice over internet = digital signal [OK]
Quick Trick: Internet uses digital signals for clear voice transmission [OK]
Common Mistakes:
