A modulated signal` C_m(t)` has the form `C_m(t) = 30 sin 300pi t + 20 (cos 100pit)`. The carrier frequency `f_c` the modulating frequency (message frequency) `f_Omega` and the modulation index `mu` are respectively given by :

Options

A. `f_(c)=200 Hz,f_(omega)=30Hz,mu=(1)/(2)`
B. `f_(c)=150 Hz,f_(omega)=50Hz,mu=(2)/(3)`
C. `f_(c)=150 Hz,f_(omega)=30Hz,mu=(1)/(3)`
D. `f_(c)=200 Hz,f_(omega)=50Hz,mu=(1)/(2)`

Answer

B
