15- a) Why optical fiber is considered advantageous over other copper media? Explain. Also, explain about different propagation techniques.
- b) A bit stream is 10011101 is transmitted using the standard CRC method. The generator polynomial is x*+1. Derive the actual bit string transmitted. Show that the error is detected if any one bit in the received bit stream is inverted.
A worked answer is on its wayMeanwhile, read the Data Communication notes for this topic.
