The unit of modulation index is * 2 points Hertz Amplitude Voltage None
Question
The unit of modulation index is * 2 points Hertz Amplitude Voltage None
Solution
The modulation index, also known as modulation depth, is a key parameter in many forms of modulation (like amplitude modulation, frequency modulation, phase modulation etc.). It essentially defines the variation in amplitude, frequency or phase of the carrier signal, depending on the properties of the modulating signal.
The modulation index is a ratio and, as such, is unitless. Therefore, the correct answer to your question is "None".
