If modulation is 100% then signal amplitude is ____________arrier amplitude?
Correct answer: A. Equal to
- A. Equal to
- B. Greater than
- C. Less than
- D. None of the above
Explanation
The modulation index is the ratio of signal amplitude to carrier amplitude, so 100% modulation means a modulation index of one. Thus, the signal amplitude equals the carrier amplitude.
