1) what is a smith chart used for 2) how is impedance matching done and why do we need it (basically can talk about ideal power supply needing a low internal resistance and high load to function properly. so one stage of transistor amplifier has to have low o/p resistance and high i/p resistance for next stage- do look up all basic electronics) ( also about sinking high currents without damage) 3) name all flipflops u know and working esp. master slave.4) c progaming - program to find how many 1's are present in an integer variable using bitwise operators. something about dynamic allocation, static functions, macros5) c++ virtual functions6) what types of control r there 7) QPSK 8) though i did mention that i was most comfortable with digital systems, microprocessors, i was asked only one or 2 questions on this topic like what is program counter, stack operation, etc.9) a lot about final year project.10) all electives, and subjects mentioned in CV.
There are 2 parts 1. Technical 2. Aptitude ( whole based on related figures not mathematical questions )
Aptitude: IDENTIFY THE UNKNOWN FIGURE FROM GIVEN RELATED FIGURES> 3 - sets of figures(SHAPES ) ARE GIVEN .EACH SET HAVING THREE FIGURES LAST SHAPE OF THIRD SET Will be missing and you HAVE TO IDENTIFY it BY CHECKING OTHER COMBINATIONS
A1 A2 A3 B1 B2 B3 C1 C2 X Find X? Given 8 number of choices. (some times X is decided by whole combinations ie, A1, A2 ,A3,B1,B2,B3,C1,C2)
Some combinations will be complicated .So be calm and quite when attendung the aptitude test.Care must be taken to utilize the allocated time perfectly since you have only 30 minutes for 36 questions and you have to deal with some complex figures( I think in the middle part given combinations were complex ;complex means very complex). My advise is to be practise well before attending the test.Since Tchnical part is not hard your fate is decided by aptitude Test only.
Technical:
There are 40 Questions and 4 choises for each Duration : 30 minutes
-----NOTE :--------------------------------------------------------------------------------------------------------------I list here some Questions and some choices that i do remember ,as it is.Some times there may be mistakes in Questions andchoices.My intension is to present how the test would be.-------------------------------------------------------------------------------------------------------------------------

SECTION TWO This section checks the concepts of class 12th mechanics.All the question contained figure.Just go through the very basic ideas of 1. gear arrangement. along with pulleys and belt drives.2. different gear arrangements.(external and internal)3. belt drives (open and closed) u will be given combination of gear and belts. Direction of motion ofone gear will be given and u have to predict the motion of other gears. There are 8 to 10 problems like this. Then balancing of masses . in this masses are hung on one side of lever, u have to predict the balancing mass on other side of lever. Simple concepts of projectile motion , moment of inertia, shape of water Coming out of tank ……………… Simple concepts of wheel balancing. Though the problems require very simple concepts but u will have to Think carefully before selecting any option.U should maintain the speed. One question on battery circuit. ------------------------------------------------------------------------------------------------------- SECTION THREE In this section 3*3 matrix was given.One box in the matrix was empty nd u have to choose The answer among 8 options. Just see the releationship existing between diffirent rows and columns And decide the answer.

1) what is a smith chart used for 2) how is impedance matching done and why do we need it (basically can talk about ideal power supply needing a low internal resistance and high load to function properly. so one stage of transistor amplifier has to have low o/p resistance and high i/p resistance for next stage- do look up all basic electronics) ( also about sinking high currents without damage) 3) name all flipflops u know and working esp. master slave.4) c progaming - program to find how many 1's are present in an integer variable using bitwise operators. something about dynamic allocation, static functions, macros5) c++ virtual functions6) what types of control r there 7) QPSK 8) though i did mention that i was most comfortable with digital systems, microprocessors, i was asked only one or 2 questions on this topic like what is program counter, stack operation, etc.9) a lot about final year project.10) all electives, and subjects mentioned in CV.
There are 2 parts 1. Technical 2. Aptitude ( whole based on related figures not mathematical questions )
Aptitude: IDENTIFY THE UNKNOWN FIGURE FROM GIVEN RELATED FIGURES> 3 - sets of figures(SHAPES ) ARE GIVEN .EACH SET HAVING THREE FIGURES LAST SHAPE OF THIRD SET Will be missing and you HAVE TO IDENTIFY it BY CHECKING OTHER COMBINATIONS
A1 A2 A3 B1 B2 B3 C1 C2 X Find X? Given 8 number of choices. (some times X is decided by whole combinations ie, A1, A2 ,A3,B1,B2,B3,C1,C2)
Some combinations will be complicated .So be calm and quite when attendung the aptitude test.Care must be taken to utilize the allocated time perfectly since you have only 30 minutes for 36 questions and you have to deal with some complex figures( I think in the middle part given combinations were complex ;complex means very complex). My advise is to be practise well before attending the test.Since Tchnical part is not hard your fate is decided by aptitude Test only.
Technical:
There are 40 Questions and 4 choises for each Duration : 30 minutes
-----NOTE :--------------------------------------------------------------------------------------------------------------I list here some Questions and some choices that i do remember ,as it is.Some times there may be mistakes in Questions andchoices.My intension is to present how the test would be.-------------------------------------------------------------------------------------------------------------------------
1. a( [ B ( [A^ C]] where '(' and '^' are symbols related to SET and '^' is not exact symbol , it is curved not conical(due to limitation of key board ), represents"union"
a. has no sense b.It is associative as well as commutative
2.2's complement of given Binary number
3. Octal Equivalent of a Binary number 4.Given -- Ac + AB + BC =
a. AC -- b. BC+AC
5. Question related to linked list
