In the question below, a, b and c are the middle, lowest and highest values of the last three digits in the student number. (For example, if the student number is 1182836; a is 6, bis 3, and c is 8. If any of these numbers is zero, take 1 instead). The message signal m(t) = a cos(4000) + sin(500t + 1/3) modulates the carrier signal c(t) = a cos(8000ft), using DSB-amplitude modulation. Find the time domain and the frequency domain representation (Fourier transform) of the modulated signal.
