Homework Statement
Let the baseband signal be
s(t)=cos(2πfst+π3), where fs=5kHz. Radio carrier is
c(t)=sin(2πfct), where fc=100MHz. Using the amplitude modulation of g(t)=(1+s(t))c(t), what is the frequency spectrum of the modulated signal g(t)?
What are the amplitude and phase shift of each frequency component in g(t)?
Homework Equations
g(t)=(1+s(t))c(t)
The Attempt at a Solution
g(t)= (1+ cos(2πfst+π3)) sin(2πfct)
g(t)= sin(2πfct)+ cos(2πfst+π3) sin(2πfct)
g(t)=
