Question:
Which of the following analog modulation schemes requires the minimum transmitted power and minimum channel bandwidth?
Which of the following analog modulation schemes requires the minimum transmitted power and minimum channel bandwidth?
Show Hint
When choosing modulation schemes for power and bandwidth efficiency, SSB is typically the best choice in communication systems.

- VSB
- DSBCS
- SSB
- AM
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Single Sideband (SSB) modulation is the most power and bandwidth-efficient compared to VSB, DSBCS, and AM. In SSB, only one of the sidebands (either upper or lower) is transmitted, while in AM, both sidebands and the carrier are transmitted, consuming more power and bandwidth. SSB effectively minimizes the transmitted power and bandwidth usage.
