Modulation Index with respect to Amplitude Sensitivity Solution

STEP 0: Pre-Calculation Summary
Formula Used
Modulation Index = Amplitude Sensitivity of Modulator*Amplitude of Modulating Signal
μ = Ka*Am
This formula uses 3 Variables
Variables Used
Modulation Index - Modulation Index states the level of modulation that a carrier wave undergoes.
Amplitude Sensitivity of Modulator - The Amplitude Sensitivity of Modulator is a constant variable of the modulator.
Amplitude of Modulating Signal - (Measured in Volt) - Amplitude of Modulating Signal is the maximum displacement of the signal from its equilibrium or rest position, measured in units of the original signal amplitude.
STEP 1: Convert Input(s) to Base Unit
Amplitude Sensitivity of Modulator: 0.05 --> No Conversion Required
Amplitude of Modulating Signal: 6.12 Volt --> 6.12 Volt No Conversion Required
STEP 2: Evaluate Formula

How modulation index varies when assigned different values to it?

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 Amplitude Sensitivity?

FAQ

What is Modulation Index with respect to Amplitude Sensitivity?
Modulation Index with respect to Amplitude Sensitivity is the absolute value of the product of amplitude sensitivity parameter (Ka) and message signal m(t) and is represented as μ = Ka*Am or Modulation Index = Amplitude Sensitivity of Modulator*Amplitude of Modulating Signal. The Amplitude Sensitivity of Modulator is a constant variable of the modulator & Amplitude of Modulating Signal is the maximum displacement of the signal from its equilibrium or rest position, measured in units of the original signal amplitude.
How to calculate Modulation Index with respect to Amplitude Sensitivity?
Modulation Index with respect to Amplitude Sensitivity is the absolute value of the product of amplitude sensitivity parameter (Ka) and message signal m(t) is calculated using Modulation Index = Amplitude Sensitivity of Modulator*Amplitude of Modulating Signal. To calculate Modulation Index with respect to Amplitude Sensitivity, you need Amplitude Sensitivity of Modulator (Ka) & Amplitude of Modulating Signal (Am). With our tool, you need to enter the respective value for Amplitude Sensitivity of Modulator & Amplitude of Modulating Signal and hit the calculate button.
