- C.A neighbouring-topic answer that does not belong to Amplitude and frequency modulation.
- D.An answer that reverses the quantity, unit, graph feature, or physical relationship.
Model answer
What a good answer should say
- The correct option is Describe the purpose of modulation.
- This is the correct definition focus for Amplitude and frequency modulation.
Explanation
Why this works
