How modulation index varies when it is assigned some values?
The modulation index or modulation depth is often denoted in percentage called as Percentage of Modulation. We will get the percentage of modulation, just by multiplying the modulation index value with 100.
For a perfect modulation, the value of modulation index should be 1, which implies the percentage of modulation should be 100%.
For instance, if this value is less than 1, i.e., the modulation index is 0.5, then the modulated output would have peak changes after some gaps. It is called as Under-modulation. Such a wave is called as an under-modulated wave.
If the value of the modulation index is greater than 1, i.e., 1.5 or so, then the wave will be an over-modulated wave. The output experiences a phase reversal.
How to Calculate Modulation Index with respect to Maximum and Minimum Amplitude?
Modulation Index with respect to Maximum and Minimum Amplitude calculator uses Modulation Index = (Maximum Amplitude of AM Wave-Minimum Amplitude of AM Wave)/(Maximum Amplitude of AM Wave+Minimum Amplitude of AM Wave) to calculate the Modulation Index, The Modulation Index with respect to Maximum and Minimum Amplitude is a measure of the depth of modulation in an amplitude modulated (AM) wave. Modulation Index is denoted by μ symbol.
How to calculate Modulation Index with respect to Maximum and Minimum Amplitude using this online calculator? To use this online calculator for Modulation Index with respect to Maximum and Minimum Amplitude, enter Maximum Amplitude of AM Wave (A_{max}) & Minimum Amplitude of AM Wave (A_{min}) and hit the calculate button. Here is how the Modulation Index with respect to Maximum and Minimum Amplitude calculation can be explained with given input values -> 0.129826 = (19.2032-14.7968)/(19.2032+14.7968).
