WebApr 10, 2024 · What is the modulation index of AM, if the voltage amplitude of the carrier wave is 2kV. asked Feb 26, 2024 in Communication Systems by RajuKumar (27.5k points) communication systems; class-12; 0 votes. 1 answer. If maximum amplitude of amplitude modulated wave is 14 volt and minimum amplitude is 6 volt then find the modulation index. WebIn this paper, the effect of the modulation index and the carrier frequency on the harmonic contents of the output voltage waveform of the sinusoidal-pulse-width-modulated (SPWM) voltage-source inverter (VSI) is presented. Both, the modulation index and the carrier frequency are affecting the harmonic contents of the inverter output voltage …

Web1) increases with deviation and decreases with modulation frequency. 2) increases with both deviation and modulation frequency. 3) is equal to twice the deviation. 4) decreases with … WebFrequency modulation uses the instantaneous amplitude of a modulating signal (voice, music, data, etc.) to directly vary the frequency of a carrier signal. Modulation index, β, is used to describe the ratio of maximum frequency deviation of the carrier to the maximum frequency deviation of the modulating signal.
