Question

The message signal $m(t) = a \cos(2 \pi f_m t)$ is used to frequency modulate the carrier $A_c \cos(2 \pi 10000t)$. Find the modulation index of FM signal for $a = 3$, $A_c = 10$, $k_f = 1$, $f_m = 7$.

Step 1

Step 1: The formula for frequency modulation is given by: s(t) = A_c * cos(2πf_c t + k_f * m(t)) where: s(t) is the FM signal A_c is the carrier amplitude f_c is the carrier frequency k_f is the frequency sensitivity constant m(t) is the message signal Show more…
