Vedclass · Answer

(C) The modulation index $\mu$ of an amplitude-modulated signal is defined as the ratio of the peak amplitude of the modulating signal $(E_m)$ to the peak amplitude of the carrier signal $(E_c)$: $\mu = \frac{E_m}{E_c}$ For $100 \%$ modulation,the modulation index $\mu$ must be equal to $1$. Substituting $\mu = 1$ into the formula: $1 = \frac{E_m}{E_c}$ This implies that $E_m = E_c$. Therefore,the correct option is $C$.

If $E_c$ and $E_m$ are peak values of carrier and modulating signals,respectively,then for $100 \%$ modulation,
