Problem 1. (7%) For each of the following modulation cases below, sketch (i) the message wave- form m(t), (ii) the modulated waveform s(t), (iii) the message magnitude spectrum M(S), and (iv) the modulated spectrum S(); and thereby (v) determine the transmission bandwidth Bl. (a) Classical AM, m(t) = A rect(t/Tp), where Tg = 10-3 seconds; A = L +3 where L is the last digit of your student ID number; assume A = 2 and ſe = 100MHz; Choose an appropriate amplitude sensitivity ke such that overmodulation is avoided. (b) SSB-SC, m(t) is generated by: cos(2* fit) x m(t) C08(2821) Figure: Generator of m(t). where the carrier has A. = 3 and fe - 30Hz; the input frequencies are fi-5Hz and f = 9Hz.
