Question 8 (18 marks) The number in the box. Convert cach digit into corresponding BCD representation to generate a binary sequence b[n] of length 16 bits. Number 1 23 4 Your b[n] 3 5 0 9 Sample in BCD 0011 0101 0000 1001 The output sequence for this sample is 0011 0101 0000 1001 (a) Generate your 16-bit scqucnce b[n] based on your number. (1 mark) (6) For your bit sequence b[n] in (a), generate and plotthe baseband waveforms.a(t) with rectangular pulses for the following linc-codingschemes. Usc nsamp = 20 samples/bit and bit period To= 1. (i) Polar NRZ xpr(t) (ii) Manchester Xma(t) (6 marks) (c) Filter the two waveforms in (b) through a fourth-order Butterworth filter with 3-dB cutoff bandwidth B:absuch that B3ab=0.7/T,. Plot the waveforms as yp(t) and yman(t) (6 marks) (d) Compare the waveforms xpw (t), Xman (t), ypy(t) and yman (t) and comment on your results. (3 marks) If ypa(t) is the received waveform after passing a channel, what is the problem of y(t)? (2 marks) Question 8 (18 marks) The number in the box.
