Question Paper
1. What are the basic functions of transponder in satellite communication system Draw and explain the block diagram of transponder model.
Discuss the various uplink and downlink frequency bands used in satellite communication system.
What is pseudonoise sequence? How is CDMA system capacity calculated in satellite communication?
3. What is meant by frequency re-use Explain frequency re-use by orthogonal polarizations.
4. Derive the general link design equation. Find the expression for C/N and G/T ratios.
5. Draw and explain the block diagram of PLL (Phase Lock Loop) with different modes of operation.
Determine the number of lines that get traced during each vertical retrace in 625 lines TV systems.
What is flicker? Explain how can it be eliminated in interlaced scanning.
What do you understand by image multiplication and signal multiplication in an image orthicon camera tube?
Sketch and briefly explain the sectional view of TV picture tube.
Why is a portion of lower side band of AM picture signal transmitted along with the carrier and full VSB Does it need any correction somewhere in the TV link? If so, where is it carried out?
Why are pre-emphasis and de-emphasis circuits provided at FM transmitter and receiver respectively?
9. Explain the difference between primary colours and complementary colours. Explain how the and colour difference signals are developed from the camera outputs. Why is the Y signal set equal to (0·3R 0·59G -0·11B)?
10. Draw and explain the block diagram of PAL encoder and decoder. Compare its performance with NTSC system.
