Consider the 4B/5B encoding scheme used along with a second encoding scheme of NRZI. Using the information found at the end of the exam, for the data bits 01011001 a. (3 points) What is the resulting encoded code word for the first stage of 4B/5B encoding? b. (2 points) What is the baud rate after 4B/5B first stage encoding, if the original data rate is R? c. (4 points) Sketch the resulting waveform after the second stage of NRZI encoding considering the 4B/5B encoded signal is the input. d. (3 points) What is resulting baud rate, after the 2 encoding techniques are applied, if the original data rate is R?
