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....
