A modulated signal $\displaystyle C_m(t)$ has the form $\displaystyle C_m(t)=30 \sin 300 \pi t+10 \quad(\cos 200 \pi t$ $\displaystyle -\cos 400 \pi t)$. The carrier frequency $\displaystyle f_c$, the modulating frequency (message frequency) $\displaystyle f_\omega$, and the modulation index $\displaystyle \mu$ are respectively given by :
