In a high-quality coaxial cable operating at 100mbps, the powe
approximately every 2.5km. if the original signal power is 0.26
far will a signal be transmitted before the power is attenuated
ung at 100mbps, the power drops by a factor of 10
"the original signal power is 0.2w (= 2 x 10-1), approximately how
uue as part of your answer a table showing the signal power vs. distance in 2.5km intervals
(similar to table 1.2 in section 1.4.4).
al fibre were to be used instead of the coaxial cable, how would you expect your
ned distance value to change? briefly explain your answer (see section 1.4.4). note: you
are not required to include a new table.

Now you’re on your own. include a short summary of this section with plots in your lab report. write a matlab script file to do steps (a) through (d) below. include a listing of the script file with your report. 1 the soundsc(xx,fs) function requires two arguments: the first one (xx) contains the vector of data to be played, the second argument (fs) is the sampling rate for playing the samples. in addition, soundsc(xx,fs) does automatic scaling and then calls sound(xx,fs) to actually play the signal. mcclellan, schafer, and yoder, dsp first, 2e, isbn 0-13-065562-7. prentice hall, upper saddle river, nj 07458. c 2015 pearson education, inc. 4 mcclellan, schafer and yoder, signal processing first. prentice hall, upper saddle river, new jersey, 2003. c 2003 prentice hall. (a) generate a time vector (tt) to cover a range of t that will exhibit approximately two cycles of the 4000 hz sinusoids defined in the next part, part (b). use a definition for tt similar to part 2.2(d). if we use t to denote the period of the sinusoids, define the starting time of the vector tt to be equal to t , and the ending time as ct . then the two cycles will include t d 0. finally, make sure that you have at least 25 samples per period of the sinusoidal wave. in other words, when you use the colon operator to define the time vector, make the increment small enough to generate 25 samples per period. (b) generate two 4000 hz sinusoids with arbitrary amplitude and time-shift. x1.t / d a1 cos.2
