hello friends, 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,osme of them are as given below;
1-SNR is defined as: 4 options.
2-To calculate the number of RAMchips 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) 4options
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
