problem 1: What are synchronization pulses and why they are required?
problem 2: What do you mean by the term interlaced scanning?
problem 3: Why has the frame repetition rate been selected to be 25 and not 24 as in the motion pictures?
problem 4: Draw composite video signal waveforms for the picture information.
problem 5: How is the sync pulses transmitted all along the picture signal?
problem 6: Justify the selection of 625 lines for the TV transmission. Why the total number of lines is kept odd in all the TV systems?
problem 7: What is the importance of selecting the number of lines 625 not 623 or 627 in a TV system.
problem 8: What is the requirement of interlaced scanning?
problem 9: Establish the relationship between the picture cell and bandwidth.
problem 10: What is the main purpose of the synchronizing circuits?
