1) Draw the graph of NRZ-L scheme and Manchester scheme using the following data streams, assuming that the previous last signal level has been positive. 00110011 (4 Marks) What is the Nyquist sampling rate for a band-pass signal with bandwidth of \( 200 \mathrm{KHz} \) if the lowest frequency is \( 100 \mathrm{KHz} \) ? (2 Marks) Identify TWO(2) problems that make unipolar scheme undesirable. \( \quad \) (2 marks) A signal is carrying data in which two data elements is encoded as three signal elements. The bit rate is \( 50 \mathrm{Kbps} \) and the value of \( c=1 / 2 \). Find the value of \( r \) and calculate the average value of the baud rate. (2 Marks)
