23. What's the difference between looping 0s and 1s in K map?
24. Difference between microprocessor and micro controller
25. Microprocessors you are familiar with
26. How will you send and receive data to a micro-processor? (One method is I/O mapped I/O which is the other one?)
27. Radar range equation?
28. Does the radar range depend upon the frequency of the signal transmitted?
29. What is Doppler shift? What is its importance?

31. What is a membership function?
32. What are the design criteria for very low frequency amplifier?
33. Can you measure distance with the help of CW radar? If so how?
34. How will you design a stable oscillator? (Not with crystal oscillator because temperature affects it)
