Engr. AA transmits sound signal in the vacuum which can be expressed mathematically below: x(t) = cos(2000mt) + jsin(2n100t) + cos(-2000mt) + jsin(-2m100t) - 2cos (6000mt) However, though the signal was travelled through the vacuum, Engr. AA sought to convert the original signal to digital signal and thereafter translating to form of analog by means of modem. He wants to prove that sound signal can travel in the vacuum irrespective of the medium. Consequently, he drawn the block diagram of the modem (see fig. 1.35) and performed the following simulation below. Assume that you are Engr. AA.

In figure 1.35 if fc = fs = 8kHz, sketch the spectrum of the signal y(t) for 0 ≤ f ≤ 8 kHz. Briefly point out the possible problems or limitations for processing x(t), if any.

Engr. AA transmits sound signal in the vacuum which can be expressed mathematically below: x(t) = cos(2000rt) + jsin(2n100t) + cos(-2000rt) + jsin(-2m100t) - 2cos (6000rt) However, though the signal was travelled through the vacuum, Engr. AA sought to convert the original signal to digital signal and thereafter translating to form of analog by means of modem. He wants to prove that sound signal can travel in the vacuum irrespective of the medium. Consequently, he drawn the block diagram of the modem (see fig. 1.35) and performed the following simulation below. Assume that you are Engr. ÄA.
