Vedclass · Answer

(A) The modulation index $\mu$ is defined as the ratio of the amplitude of the message signal $(A_m)$ to the amplitude of the carrier wave $(A_c)$.Given:Amplitude of message signal,$A_m = 15 V$Amplitude of carrier wave,$A_c = 30 V$Formula:$\mu = \frac{A_m}{A_c}$Calculation:$\mu = \frac{15 V}{30 V} = 0.5$Therefore,the modulation index is $0.5$.

$A$ message signal of frequency $10 kHz$ and peak voltage of $15 V$ is used to modulate a carrier frequency of $1 MHz$ and peak voltage of $30 V$. Determine the modulation index.
