Polytechnic University, Dept. Electrical and Computer Engineering EE4414 Multimedia Communication System II Yao Wang _______________________________________________________________________ ____________ Homework 1 (Analog Monochrome TV Systems) Reading Assignment: 9. Lecture slides 10. Y. Wang, et al. Video processing and communications, Chapter 1 (mainly Sec.1.3,1.4) 11. B. P. Lathi, Modern digital and analog communication systems, Chapter 4 (you can skip pp.155-161,166-170,174-178, Sec.4.7,4.8.) Written Assignment 12. Describe the difference between progressive and interlaced scan. What is the advantage and disadvantage of interlaced scan compared with progressive scan, when the line rate per second (lines/s) is the same? 13. What are some of the factors that determine the minimal required frame rate (frames/s) and line number (lines/frame) for the eye not to see separate frames or lines? 14. Consider a raster video converted from a 3D video signal with 10 frames/second,

Unformatted text preview: 100 x 100 pixels/frame. What is the maximum possible temporal frequency (Hz or cycles/s)? 15. What is the bandwidth of the NTSC video? 16. How is audio multiplexed with video into a single signal? What is the carrier frequency used for audio? 17. Which modulation technique is used for modulating a TV signal to a carrier frequency? What is the total bandwidth allocated for a TV channel? Illustrate with a figure the spectrum of a modulated TV channel. 18. Describe the difference between DSB, SSB, and VSB. Illustrate with spectrum plots in the frequency domain. 19. Draw block diagrams for modulation and demodulation using VSB-SC. And explain briefly the function of each block in the diagrams. 20. With amplitude modulation (e.g. DSB), one can either suppress the carrier or transmit the carrier (leading to DSB-SC and DSB-C), discuss the difference in demodulation for DSB-SC and DSB-C. What are the major advantage and disadvantages of each? 21....
