problem 1: What are the characteristics by which the colored visual information can be represented?

problem 2: Illustrate the limitations of the NTSC system?

problem 3: Describe the advantages and drawbacks of SECAM system.

problem 4: Describe how by frequency interleaving the color information is accommodated within the similar channel bandwidth of 7MHz.

problem 5: Draw a block diagram of the color TV receiver.

problem 6: Describe with the block diagram how both (B-Y) and (R-Y) signals are joined around the similar sub carrier frequency by Quadrature modulation. Why is the color signal bandwidth requirement much less than those of the Y signal?

problem 7: Describe the factors that affect the choice of sub carrier frequency in a color TV system.

problem 8: Validate the choice of 3.579545MHz as the sub carrier frequency in the NTSC system. How does it influence the line and field frequencies?
