i. 5. The system shown below is to be used to generate a modulated signal km(t) cos wct, where the m(t) is the signal with the spectrum shown. Explain if this system could be used to generate the required modulated signal. If so, what kind of filter is needed? ii. Determine the signal spectra at points b and c, and indicate the frequency bands occupied by these spectra. üü. What is the minimum usable value of oc? iv. Would this scheme work if the carrier generator output were cos? wct? Explain. Mw) km(t) cos wct m(t) Filter cos3 ' ത -21B 27B w (a) (b)
