The analytical expressions of a few modulated signals are given in Eq (1) to Eq (5). S (t) = m(t) cos(wet) Eq (1) S (t) = [m(t) + A]cos(wet) Eq (2) S3 (t) = m(t) cos(wet) F m(t) sin(wet) Eq (3) S4 (t) = Acos[wet + km(t)] Eq (4) S5 (t) = Acos[wet + k5 tm()d] Eq (5) (i) (ii) m(t) is the modulating (message) signal of bandwidth B cos (@ct) is the carrier signal k4, k5 are arbitrary constants Which type of modulation is being represented by each equation? [5 marks] What is the bandwidth of each of the modulated signals of Eq (1) to Eq (5)? [5 marks]
