3 ciplexing? [3 marks] C. A message x(t) with bandwidth 200 Hz and signal power Sx = 0.5 W is to be transmitted by modulating a 20 kHz carrier of amplitude A. =15. a) If the modulation scheme employed is USSB, what is the signal power S, of the transmitted signal and between what frequency limits does the transmitted signal power lie (consider only positive frequency space). [5 marks] b) If the modulation scheme is DSB-FC with m=0.8, determine the following: i. Carrier power, P. [2 marks] ii. Power of the sideband, Pse [3 marks] iii. What frequency limits does the transmitted signal power lies (consider only positive frequency space) [3 marks]
