Answer:

1) 10cos ( 2πfct + 10sin 2πfmt )

2) 50 watts

3) 1000 Hz

Explanation:

m(t) = 10cos(1000πt)

c(t) = 10cos(2πfct )

modulation index (  = 10

1) expression for modulated signal ( u(t) )

u(t) = Ac(cos 2πfct ) + A (cos 2πfct m(t) ) Am cos2πf mt

      = 10cos 2πfct + 100 cos 2πfct  cos2π500t

      = 10cos ( 2πfct + 10sin 2πfmt )

2) power of modulated signal

power of modulated signal  μ^2 / 2 ]

           = 10^2/2 ]

           = 50 watts

3) Bandwidth

B = 2fm  = 2 * 500 = 1000 Hz
