QUESTION 8 In selecting a line coding technique, we need to consider the need for receive clock synchronization, and how much frequency bandwidth is occupied by the resulting signal. What is true about the Manchester line coding technique. QUESTION 10 Analog information can be converted into digital data using techniques such as PCM (pulse code modulation). Select the correct statement(s). 1. 1. a. in order to convert an analog signal that consists of an infinite number of values, it must be sampled using the Nyquist sampling theorem a. Manchester occupies less frequency spectrum {i.e. frequency bandwidth), than simpler line coding techniques such as NRZ b. digitized analog signals always experience quantization loss b. Manchester ensures signal transitions for each bit sent, thus helping to ensure receive clock synchronization; hawever, it occupies twice the frequency bandwidth compared to NRZ c. signal aliasing is experienced when samplig falls under the recommended Nyquist sampling c. Manchester ensures greater receive clock synchronization and efficient bandwidth usage compared to NRZ d. all of the above are correct 10 points d there are no true statements listed above QUESTION 11 You want to capture a live music concert and covert it into digital format for transmission. The human ear hasa frequercy bandwidth of approximately 20,000 Hz. Select the best sampling rate and bit depth. 1. 10 points QUESTION 9 Os do not exist prior to being line coded. Select the correct statement s) regarding 4BSB a. since 4BSB eliminates long string of logics" and s", simpler lne coding techniques 1. 4B5B differs from line coding techniques in that is ensures that strings of consecutive "s" and a. fs 40,000 samples/s, Bit depth 1 bit per sample b. fs-40,000 samples/s, Bit depth- 16 bit per sample c. fs-10,000 sampless, Bit depth 16 bit per sample d. fs-20,000 sampless, Bit depth 1 bit per sample such as NRZ can be used b. since one bit out of every five bits sent is not real information, the data link suffers from a 1/5 or 20% overhead cost (i.e., reduction in data throughput) c. only 80% of the data sent using 4B5B is real inform ation 10 points d. all of the above are correct statements 10 points
