Multiple Choice Options
- A
Signal power also increases
- B
Bandwidth requirements increase
- C✓ Correct Option
Signal-to-noise ratio decreases
- D
Carrier frequency decreases
Detailed Technical Solution & Explanation
According to standard engineering principles, for If the modulation index of FDM (Frequency Division Multiplexing) is increased, then:, the correct choice is Signal-to-noise ratio decreases.
Option Analysis:
•
Option A (Signal power also increases): Incorrect. Does not satisfy the technical condition or specifies an alternate/invalid property.
•
Option B (Bandwidth requirements increase): Incorrect. Does not satisfy the technical condition or specifies an alternate/invalid property.
•
Option C (Signal-to-noise ratio decreases): Correct. Valid technical statement directly addressing the question requirement.
•
Option D (Carrier frequency decreases): Incorrect. Does not satisfy the technical condition or specifies an alternate/invalid property.
