    The test of JSPL held on 17th February 2008 was more or less of an easy type for instrumentation stream. Many questions were from power electronics and communications. The ques that I remember were:


    Verbal (20 ques):

    1. 10 ques based on two RC passages,dealing with computer languages.

    2. remaining ques on articles, prepositions and word meanings.


    Numerical (20 ques):
    1. all ques based on simple but lengthy calculations involving %ages, profit and loss, ratio-proportion,etc.


    Attention to detail(15 ques):
    1. ques based on pattern recognition, logical reasoning and types like if + is -, - is *, etc.


    Technical (60 ques-INSTRUMENTATION):  

    I remember 51 ques. They are:  

    1. what does ?value? mean in value engg.
    2. what is value engg used for
    3. two ques on statement of nyquist-shannon theorem
    4. i/p and o/p impedance of instrumentation amplifier
    5. given open loop TF for unity f/b calc damping ratio
    6. given G(s)H(s) calc type of system
    7. thru which signal does µP communicate with memory
    8. 12 address lines address how much of memory
    9. no of timers of 8051
    10. prog device used with 8051
    11. µcontrollers used widely in which industry
    12. ques on what is LPP
    13. which technique used for optimization in OR
    14. which of these deals with reducing waiting time(ans: queuing theory)
    15. given BW and SNR of a communication channel calc its maxm transmission rate in kbps when affected by white Gaussian noise
    16. what is a µcontroller
    17. no of components in VLSI

    19. what are the procedures for sampling of a signal
    20. which is the most commonly used non-impulse type of pump
    21. how do you go from time domain to freq domain(both fourier and laplace were in the options)
    22. what is thyristor
    23. what is triac
    24. diff betw triac and SCR
    25. why is equalizing ckt used in series with SCR
    26. what freq crystal should be used betw pin 1 n 2 of a µP
    27. if for a resistive load in an SCR ckt the current is ripple free and equal to 20 A what will it be when 20 mH inductor connected to the load
    28. if load current in an SCR is I, what is the average thyristor current for a 1-? converter
    29. maxm efficiency of AM power
    30. given signal freq and intermediate freq calc image freq
    31. when are equalizing pulses applied in TV
    32. what is a spirometer
    33. what is used to measure heart sounds
    34. minm duration of firing pulses for a thyristor
    35. which of these transforms is also called tustin ?s method( or something like that)
    36. why is RC snubber ckt used
    37. what type of waveform produced by RC oscillator
    38. diff betw inverter and oscillator output
    39. for a 6 phase 60 Hz half wave rectifier what is the triple freq of the output
    40. which of the following modulation is digital: PCM/ PAM/ PWM/ PTM
    41. which method of ctrl removes offset
    42. eqn of PID
    43. what filter used for extracting SSB output
    44. CMRR is expressed commonly in
    45. integrated value of step fn.
    46. differentiated value of const fn.
    47. what is the kidney dialysis method(artificial) called
    48. quantity analogous to current in pneumatics
    49. quantity analogous to mass in rotational motion
    50. which of these theorems not used in filters( ans: norton?s theorem)
    51. which of these is UHF(1.68MHz,16.8Mhz,168Mhz,1680MHz

    That?s all folks??..
