Question 2:
A modified NRZ code known as enhanced-NRZ (E-NRZ) is sometimes used for high-density magnetic tape recording. E-NRZ encoding entails separating the NRZ-L data stream into 7-bit words; inverting bits 2, 3, 6, and 7; and adding one parity bit to each word. The parity bit is chosen to make the total number of 1s in the 8-bit word an odd count. What are the advantages of ENRZ over NRZ-L? Disadvantages?
Question 3:
Two companies consider pooling resources to perform a joint venture. The CEO of the first company meets with his legal team, and the legal team consults a number of middle managers in the proposed product area. Meanwhile, the CEO of the first company sends an email to the CEO of the second company to offer a couple suggestions concerning the joint venture. Does this scenario follow the OSI model? Explain.
Question 4:

What is the channel capacity for a teleprinter channel with a 300-Hz bandwidth and a signal-to-noise ratio of 3 dB, where the noise is white thermal noise?
Question 5:

Can you transmit a video signal over twisted pair wire? Explain. Be sure to consider multiple scenarios.
Question 6:

Twenty-four voice signals are to be multiplexed and transmitted over twisted pair. What is the bandwidth required (in bps) if synchronous time division multiplexing is used, if we use the standard analog to digital sampling rate, and if each sample is converted into an 8-bit value?
