What is the formula for the modulation index?
Understand the Problem
The question is asking for the formula that defines the modulation index used in modulation communications, which measures the extent of modulation applied to a carrier signal.
Answer
μa = Am / Ac
The final answer is μa = Am / Ac
Answer for screen readers
The final answer is μa = Am / Ac
More Information
The modulation index describes the extent of modulation applied to the carrier signal. It is an important parameter in Amplitude Modulation (AM) and Frequency Modulation (FM) systems.
Tips
Ensure to correctly identify the amplitude of the message signal (Am) and the carrier signal (Ac) to avoid calculation errors.
