JINDAL PAPER ON 17th FEBRUARY AT KOLKATA
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:
what does ‘value’ mean in value engg.
what is value engg used for
two ques on statement of nyquist-shannon theorem
i/p and o/p impedance of instrumentation amplifier
given open loop TF for unity f/b calc damping ratio
given G(s)H(s) calc type of system
thru which signal does µP communicate with memory
12 address lines address how much of memory
no of timers of 8051
prog device used with 8051
µcontrollers used widely in which industry

and laplace were in the options)
what is thyristor
what is triac
diff betw triac and SCR
why is equalizing ckt used in series with SCR
what freq crystal should be used betw pin 1 n 2 of a µP
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
if load current in an SCR is I, what is the average
thyristor current for a 1-f converter
maxm efficiency of AM power
given signal freq and intermediate freq calc image freq
when are equalizing pulses applied in TV
what is a spirometer
what is used to measure heart sounds
minm duration of firing pulses for a thyristor
which of these transforms is also called tustin ’s method(
or something like that)
why is RC snubber ckt used
what type of waveform produced by RC oscillator
diff betw inverter and oscillator output
for a 6 phase 60 Hz half wave rectifier what is the triple
freq of the output
which of the following modulation is digital: PCM/ PAM/ PWM/ PTM
which method of ctrl removes offset
eqn of PID
what filter used for extracting SSB output
CMRR is expressed commonly in
integrated value of step fn.
differentiated value of const fn.
what is the kidney dialysis method(artificial) called
quantity analogous to current in pneumatics
quantity analogous to mass in rotational motion
which of these theorems not used in filters( ans: norton’s
theorem)
which of these is UHF(1.68MHz,16.8Mhz,168Mhz,1680MHz
