Question
Transcribed Image Text:11. The medium between the two communicating systems can transmit frequencies from 100 MHz to 1,2 GHz.
The signal used in data transmission in this system is defined as follows:
S(t) = 4Sin (3x10³nt) + 1,33Sin (9 x10³mt) + 0,8Sin(1,5 x10°πt) + 0,57Sin (2,1 x10³nt) +
0,44Sin (2,7 x10°nt) + 0,36Sin (3,3 x10³nt)
According to this information;
a.
What is the spectrum, absolute bandwidth, and effective bandwidth of signal? (10p)
b. Find the frequency, period, wavelength, and phase values of 2nd harmonic. (Assume velocity of signal is
90% of light speed) (10p)
For this transmission medium for Temperature as 294 °K, what will be the Noise power in this
bandwith? (10p)
C.
