Q2. A luminance signal and two weighted color difference signals of the PAL color TV system are given by Y= 0.3R + 0.59G + 0.1 1B V = 0.877(R-Y) U- 0.493(B-Y) where R, G, and B are the red, green, and blue components respectively The color bar picture is shown below AYR The following table shows the composition of all colors employed in the above picture Colors Magenta an Green (a) Find the amplitudes of the luminance signals of the above colors. (3 marks) (b) Find the saturation and the hue of the chrominance signals of the above colors. (6 marks) (c) Sketch the above composite video signal on scale (6 marks) (d) Draw the display of the vectorscope in the lines n and n+1 of the above color bars. Hence, explain the advantage of the PAL system over the NTSC system when phase distortion of color occurs. (12 marks) Q2.
