VVDN CHENNAI

they people mainly focus on your electronics , c, processor or controller fundamentals etc.
some of the question which they asked in interview are:

1. what is the diffrence between controller and processor.
2. what is the address lines,data lines?what is the use of them?
3. what is the risc and cisc architecture,what is the diffrence and examples?
4.  what is the scope,life,diffrent scope operators and difference between them and when to use?
5.  compilation stages.
6.  one c programe of pattern.
    1
    23
    456
    78910.
7. they have asked me to find output of some programmes in which scope related bugs were present.
8. one puzzle:
        they've provide me one square and said that i have removed 1/4th part of it.now u have to devide it into four parts and find area of each part.

9. what is half wave,full wave rectifiers, how its working and when to use, its waveforms and all the things related to that.
10.  the transformer type used in rectifier.
11. the diffrent type of transformers and its applications.
12. the output voltages according to diffrent turns ratio of transformers.
13. what is the peak voltage in waveforms.
14. signal when passes to the capacitor what happens??have to draw the output waveforms.
15. they have provided one condition that irrespective of input signal polarity i have to generate the one side polarity signal at output.so design circuit for that.
16. they have provided 16 bit address and told me to design programe to get only higher 8 bit address without shift operators.

17. A number they've provided me and ask to find next number of that number which is divisable by 4 without any kind of loop.and in single statement.
