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

if load current in an SCR is I, what is the average thyristor current for a 1-ö 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
