problem 1: Why does the vertical retrace not start with the incoming of the first serrated vertical sync pulse?
problem 2: Validate the name vestigial sideband.
problem 3: Why is it essential to affect the economy in channel bandwidth? Why SSB is not employed for picture signal transmission.
problem 4: describe different benefits and drawbacks of VSB transmission.
problem 5: Why is a part of lower side band of AM picture signal transmitted all along with the carrier and full VSB? Does it require any correction somewhere in the TV link? If so, where is it taken out?
problem 6: Why is it essential to modulate the picture and sound signal before the transmission?
problem 7: Show that in the 625-B system; a total channel bandwidth of 11.25MHz would be essential if both the sidebands of the amplitude-modulated picture are completely radiated all along with the frequency modulated picture signal.
problem 8: Show that a total channel bandwidth of 7MHz is essential for successful transmission of both picture and sound signal in the 625 lines TV system.
problem 9: Why is the sound carrier situated at 5.5MHz away from the picture carrier? Sketch frequency distribution of the channel and mark the position of picture and sound signal carrier frequencies.
problem 10: Validate the allocation of 8MHz in British TV system and 6MHz in the American system for each TV channel. Determine the separation between picture and sound carriers in each of such systems?
