Find the bandwidth and the power content of modulated signal, Electrical Engineering

Assignment Help:

The normalized signal xn(t) has a bandwidth of 10 kHz and its power content is 0.5 W, while the carrier Ac cos 2πfct has a power content of 200W. Find the bandwidth and the power content of the modulated signal, if the modulation scheme is:

(a) Conventional AM with a modulation index of 0.6 and a transmitted signal of Ac[1+ mAx(t)] cos 2πfct .

(b) DSB SC with a transmitted signal of Acx(t) cos 2πfct .

(c) SSB with a transmitted signal of Acx(t) cos 2πfct ± Ac ¯ x(t) sin 2πfct , where x(t) is a signal with a 90° phase shift in all frequency components of x(t), and the upper - sign corresponds to the USSB signal, whereas the lower + sign corresponds to the LSSB signal.

(d) FM with kf = 50 kHz.
