A modulated signal Cm(t) has the form Cm(t) = 30 sin 300 $$\pi $$t + 10 (cos 200 $$\pi $$t −cos 400 $$\pi $$t). The carrier frequency c, the modulating frequency (message frequency) f$$\omega $$, and the modulation index $$\mu $$ are respectively given by :
A
fc = 200 Hz; f$$\omega $$ = 50 Hz; $$\mu $$ = $${1 \over 2}$$
B
fc = 150 Hz; f$$\omega $$ = 50 Hz; $$\mu $$ = $${2 \over 3}$$
C
fc = 150 Hz; f$$\omega $$ = 30 Hz; $$\mu $$ = $${1 \over 3}$$
D
fc = 200 Hz; f$$\omega $$ = 30 Hz; $$\mu $$ = $${1 \over 2}$$
