Equation of messages signal `m = 2 sin omega_(m)(t)` and carrier signal `c = 4 sin omega_(C)(t)`. The equation of modulating signal will be

Options

A. `4 sin omega_(C)(t) + 2 sin omega_(m)(t)`
B. `4 sin omega_(C)(t) + 2 sin omega_(m)(t) cdot sin omega_(C)(t)`
C. `8 sin omega_(C)(t) + sin omega_(m)(t)`
D. `(1+sin omega_(m)(t))sin omega_(m)(t)`

Answer

B

Explanation

Equation of insulating signal is `f(t) = (4 t 2 sin omega m t)sin omega_(c)t`
