problem 1: describe the different steps in the evolution and construction of the composite signal.

problem 2: How the interlaced scanning decreases the flicker and conserve bandwidth?

problem 3: What do you understand by the term active and blanking periods in horizontal and vertical scanning?

problem 4: What is meant by the term vertical and horizontal resolution? Derive an expression for the highest modulating frequency in TV system and exhibit that it is almost 5MHz in the 625-B monochrome system.

problem 5: What do you understand by interlace error and how it influences the quality of picture?

problem 6: prepare brief notes on the front porch, horizontal sync pulses, back porch and active line periods in a video signal?

problem 7: Describe how the vertical and horizontal sync pulses are separated and shaped at the receiver.

problem 8: Sketch the complete pulse trains which follow at the end of both odd and even fields. Fully label them and describe how the half line discrepancy is eliminated by insertion of pre-equalizing pulses.

problem 9: Justify the requirement of pre and post equalizing pulses. Why is it essential to keep their duration equivalent to half-line period?

problem 10: Justify the requirement of a blanking period corresponding to the 20 complete lines after each active field of scanning.
