1. I will make two fuzzy statements. Pencil is long. Table is long. What is the term long signify?
2. What is a membership function?
3. What are the design criteria for very low frequency amplifier?
4. Can you measure distance with the help of CW radar? If so how?
5. How will you design a stable oscillator? (Not with crystal oscillator because temperature affects it)
6. You have designed an amplifier. After few days it is found that its gain have changed. What might be the reason?
BOARD MEMBER-3 (QUESTION LEVEL- MODERATE)
1. A plane is moving in a circular path around the transmitter of the radar. Will there be Doppler shift detected in the radar?
2. State Keplers laws
3. Why there is more geo synchronous satellite?
4. The angular difference between two satellites is 2 degree. What is the maximum number of satellites needed to cover the whole earth?
5. What is the minimum number of satellites needed to cover the whole earth?
BOARD MEMBER-4 QUESTION LEVEL- MODERATE)
1. Which is the law of conservation involved in the second of Keplers?
2. Why do you explain elliptical orbit while stating Kepler's law? Why not circular orbit?
3. What are the advantages of optical communication?
4. What are the invasive and non-invasive methods of instrumentation?
For CS guys they started with this question: What is a key board? Where u will connec? What will happen if you press the keys?..
For maths guys they asked some questions on series.. I don't know muchSome guys were selected just by describing the final year project.
Sample questions asked in ISRO board (ECE)
1) How does a satellite communication work?
2) Why numerical methods used in research?
3) Hell lot of questions in TV engineering like horizontal and vertical frequencies, what will happen if they are reversed, interlaced scanning, PAL and some other questions.
4) Basic digital questions
5) Basic communications like SSB, AM, FM, VSB and what will happen if AM and FM is interchanged in TV transmission.
6) Some questions on project.
Main model of technical question in exam are Direct theory question.
Direct numerical problem.
Indirect theory and numerical problem.
Graph based questions.
Assertion and reasoning type
Block diagram based (control theory)
