1. A digitized voice channel is made by digitizing a 7 KHz bandwidth analog signal. The signal is to be sampled twice the highest frequency (two samples per hertz) . Assume each sample requires 16 bits. What is the required bit rate?2. If the signal at the beginning of a cable with -0.5 db/km has a power of 5 mW. What is the power of the signal at 8 Km.3. What are the propagation time and transmission time for a 10 M byte message if the bandwidth of the network is 2 Mbps. The distance between the sender and the receiver is 15,000 KM and the light travels at 2.4 x 108 m/s.4. Define Frequency Hopping Spread Spectrum and how it achieves bandwidth spreading.5. Explain how Direct Sequence Spread Spectrum expands the bandwidth of the original signal6. A multiplexer combines four 200 kbps channels using a time slot of 2 bits. Show the output with four arbitrary inputs. What is the frame rate? What is the frame duration? What is the bit rate? What is the bit duration?7. There are four sources each creating 250 characters per second. If the interleaved unit is a character and 1 synchronizing bit is added to each frame , find (a) the data rate of each source (b) the duration of each character in each source (c) the frame rate (d) duration of each frame (e) the number of bits in each frame (f) the data rate of the link8. Explain multilevel multiplexing, multiple slot multiplexing, pulse stuffing and framing bits with diagrams.9. Explain the process of streaming stored audio/video by using a web server with metafile, using a media server and Real time streaming protocol (RSTP)10. Explain JPEG image compression process with diagram.
