1. The problem statement, all variables and given/known data Which frequency components are present in the amplitude-modulated (AM) signal A(t)=[1+asin(2πfmt)]A0sin(2πfct), where fm= 3.5 kHz, fc = 540 kHz, and a = 0.1? 2. Relevant equations A(t)=[1+M(t)]A0sin(2πfct), where modulating signal M(t) = sin(2πfm t + ∅), high frequency carrier = A0sin(2πfct), fc : Carrier frequency fm : Modulation frequency 3. The attempt at a solution I wrote down 'Carrier frequency and modulation frequency are presented' at first, but now I am not sure that the question requires a numerical answer or not.
