ISRO PAPER - 22 APR 2007 - DELHI
I have attended the ISRO (Electronics) exam held on 22nd April 2007 at DELHI.
The pattern was:
(1) all questions were technical
(2) no GK question
80 questions in 90 mns.
The pattern of xam was so simple & scoring for those who have also prepared for GATE.
A max. number of questions were asked from Antenna, Microwave & EMFT, apart from this main concerns were Digital Electronics, fundamental question on Maths (integration & prob) were asked.
Basically all the questions were either based on formulas or simple logic. I have attempted approx. 60-65 questions, some of them are as given below;
1-SNR is defined as: 4 options.
2-To calculate the number of RAM chips for a given one: 4 options
3-The correct value of COS(A) in terms of exponential: 4 options
4-A figure to represent which kind of Flipflop: 4 options
5-A prob. on adder with shift register to identified no. of clock used to show the output (ie1010): 4 options
6-Three questions were asked on Zener Diode to evaluate variable resirance, min. passing current & variable supplied voltage: 4 options
7-A problem on line to which passes thru point (-1,2) and making equal intercepts on both axis: 4 options
8-Transformer core requried: 4 options with high permiability & low hysteris losses etc. like difft. values
9-To evaluate the prob. to get either of 2 color balls in a bag containg 6 red & 8 black balls: 4 options
10-A wire length 2m having restiance 5 ohms, what will be the resitance if its length bcome 2 fold: 4options
