Q6. The normalized signal m, (t) has a bandwidth of 8 kHz and its power content is 2 W. The carrier A.cos(2nfet) has a power content of 200 Watts. a) If mn (t) modulates the carrier using SSB amplitude modulation, what will be the bandwidth and the power content of the modulated signal? Express the modulated signal. b) If the modulation scheme is DSB-SC, what will be the bandwidth and the power content of the modulated signal? c) If the modulation scheme is AM with a modulation index of 0.5, what will be the bandwidth and the power content of the modulated signal? d) Consider the filter below to generate VSB modulated signal. Determine the bandwidth of the VSB modulated signal. |VSB(f)| 1 f (Hz) -fe - 10000-fe 1500 -fe -fe + 1500 fe - 1500 fe f. + 1500 f. + 10000
