Fm modulationsindex
WebThe modulation index is large, i.e., higher than 1. Its spectrum consists of a carrier and infinite number of sidebands, which are located around it. This is used in entertainment broadcasting applications such as FM radio, TV, etc. Phase Modulation In frequency modulation, the frequency of the carrier varies. 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 …
