15. Draw the graph of the NRZ-L scheme using each of the following data streams, assuming that the last signal level has been positive. From the graphs, guess the bandwidth for this scheme using the average number of changes in the signal level. Compare your guess with the corresponding entry in Table 4.1. a. 00000000 b. 11111111 c. 01010101 d. 00110011 16. Repeat Exercise 15 for the NRZ-I scheme. 17. Repeat Exercise 15 for the Manchester scheme.

Step 1
Since I can't draw graphs here, I'll describe how they would look and how to estimate the bandwidth. ### NRZ-L Scheme #### Show moreā¦

The block diagram of a binary convolutional code is shown below: a) Draw the state diagram and trellis diagram for this encoder. b) Find T(D), the transfer function of the code. c) What is dfree, the minimum free distance of the code? d) What is the coding gain for this code in dB? e) What is the output sequence corresponding to the input message sequence 1101? f) Assume that the received sequence is r = (10 11 11 10). Using the Viterbi algorithm, find the transmitted bit sequence.

With the aid of a diagram critically compare between Narrow Band (NB), Spread Spectrum (SS) and Ultra Bandwidth (UWB). Design a Frequency Hopping (FH) system with 7 hops. Assuming the guard between any successive frequencies is 3 kHz and the second lowest hop is 23 kHz. Draw the time domain and frequency domain at the input and output of the FH system. Which of the following codes are a maximal length Pseudo Random Binary Sequence (PRBS): 1- 1001011 2- 0000111 Draw the correlation function of the PRBS code.
