Gate 2014 ECE question paper analysis with solutions

Based on student test experiences in the stream of EC on 15th February, 2014 – First Session:

1. Questions with numerical answers accounted for 40-50 % of the paper. Hence you cannot guess your way through the paper. General Ability section also has such questions.

2. In the papers of the past, there used to be some questions which could be solved by eliminating the wrong options. But with an increase in the “numerical answer” type questions, this method of problem solving takes a backseat.

3. With the high occurrence of “numerical answer” type questions, one has to be thorough and careful with unit conversions so as to type in the correct answer. Earlier, the four options more or less served as guidelines.

4. Among general ability questions, there was one question each from Data Interpretation, Probability, Time and Speed (Relative Velocity), Series, logical reasoning and critical reasoning.

5. Engineering Mathematics questions were of average difficulty level. There were questions from Linear Algebra (2 questions), Differential Equation (1 question), Complex Integration (1 question) and Vector Calculus.

6. There were some direct questions from a few topics while some of questions needed concept of two topics to solve them. Such questions were tough to solve. Scoring sections were Networks, Control Systems, Signal and Systems and Analog Circuits.

7. The sequence of questions was different for each candidate i.e. no two candidates will have same sequence of questions.

8. There were no “Common Data” and “Linked” questions in this paper as well.

    The Key by made easy is wrong.. most of the questions doesn’t match with actual gate questions. Also many of the solutions too are wrong… very bad !

    **15th feb EC eve. session que**
    What is the threshold for getting equal probabilities of the 2 signals transmitted by da system having PDF = e^-2x? I think I wrote abt 0.35. Pls sum1 answer it….

    **15th feb EC eve. session que**
    What is the threshold for getting equal probabilities of the 2 signals transmitted by da system having PDF = 2e^-2x? I think I wrote abt 0.35. Pls sum1 answer it….

  4. Mayur says

    **15 feb EC eve. session**
    One of da questions I remember,
    A system transmits two signals at 0 & 1. PDF of system = 2e^-2x. Det. da threshold value so that each signal has equal probability. Wat is it’s answer? I calculated it as ln(2)/2=0.35

  5. Devesh says

    @Mayur Yeah I remember that question even I had marked the same ans (ln2/2) IMO the answer is correct but lets see.

    BTW does anyone remember the answer for the Probability of error question was it Q(4) or Q(2root2)??
    I can’t seem to remember if I had used the N value or I used the value of N/2(by mistake)
    Anyone???
    PS:The question was in 15th feb evening EC session.
    Thanks.
