Graduate Aptitude Test in Engineering - GATE 2012

Graduate Aptitude Test in Engineering - GATE 2012

  Date of Online Examination: 29-01-2012 (Sunday)          Date of Offline Examination: 12-02-2012 (Sunday)

Graduate Aptitude Test in Engineering (GATE) is an all India examination administered and conducted jointly by the Indian Institute of Science and seven Indian Institutes of Technology on behalf of the National Coordination Board - GATE, Department of Higher Education, Ministry of Human Resource Development (MHRD), Government of India.

The GATE committee, which comprises of representatives from the administering institutes, is the sole authority for regulating the examination and declaring the results.

GATE is conducted through the constitution of eight zones. The zones and the corresponding administrative institutes are:

      Zone-1: Indian Institute of Science   Bengaluru
      Zone-2: Indian Institute of Technology Bombay
      Zone-3: Indian Institute of Technology Delhi
      Zone-4: Indian Institute of Technology Guwahati
      Zone-5: Indian Institute of Technology Kanpur
      Zone-6: Indian Institute of Technology Kharagpur 
      Zone-7: Indian Institute of Technology Madras 
      Zone-8: Indian Institute of Technology Roorkee

The overall coordination and responsibility of conducting GATE 2012 lies with Indian Institute of Technology Delhi,designated as the Organising Institute for GATE 2012 .

Admission to postgraduate programmes with MHRD and some other Government scholarships/assistantships in engineering colleges/institutes is open to those who qualify in GATE examination. GATE qualified candidates with Bachelor's degree in Engineering/Technology/Architecture or Master's degree in any branch of Science/Mathematics/Statistics/Computer Applications are eligible for admission to Master's degree programmes in Engineering/Technology/Architecture as well as for Doctoral programmes in relevant branches of Science with MHRD or other government scholarships/assistantships. To avail the scholarship, the candidate must secure admission to such a postgraduate programme, as per the prevailing procedure of the admitting institution. However, candidates with Master's degree in Engineering/Technology/Architecture may seek admission to relevant Doctoral programmes with scholarship/assistantship without appearing in the GATE examination.

GATE qualification is also a minimum requirement to apply for various fellowships awarded by many Government organizations.

                         

GATE 2012

Usually GATE notification come in the mid of September, but this time it’s being announced earlier.  IITD will be organizing GATE 2012. One major change happened this year. Third year engineering students are not eligible for GATE 2012. Final Year Engineering students can appear for GATE. This is a good move towards a clear admission strategy for M.Tech.


Application Process and Fee:
GATE aspirants need to apply online for GATE 2012. There no offline or paper based application in GATE 2012. There is no sale of GATE application form at different Banks and counters. Candidates need to apply through their regional GATE websites. To know your zone please refer to GATE 2012 information brochure.
The application fee is Rs. 1000/- for General/OBC candidates and Rs. 500/- for SC/ST/PD candidates.

We are also coming up with a community to help GATE 2012 .You can help and get help from students all across the nation. Just hold your breath for a moment, we are coming soon.
Wish you all a great luck ahead.

Properties of discrete-time linear convolution and system properties

Properties of discrete-time linear convolution and system properties If  and  are sequences, then the following useful properties of the discrete time convolution can be shown to be true 1. Commutativity 2. Associativity  ` 3. Distributivity over sequence addition 4. The identity sequence  5. Delay operation 6. Multiplication by a constant Note that these properties are true only if the convolution sum (4.4) exists for every n. If the input output relation is defined by convolution i.e. if For a given sequence , then the system is linear and time invariant. This can be verified using the properties of the convolution listed above. The impulse response of the systems is obviously. In terms of LTI system, commutative property implies that we can interchange input and impulse response. Fig 4.5 The distributive property implies that parallel interconnection of two LTI system is an LTI system with impulse response as sum of two impulse responses. Fig 4.6 The associativity property implies that series connection of two LTI system is an LTI system. Where impulse response is convolution of individual responses. The commutativity property implies that we can interchange the order of the two system in series. Fig 4.7 Since an LTI system is completely characterized by its impulse response, we can specify system- properties in terms of impulse response. Memoryless system: From equation (4.4) we see that an LTI system is memory less if and only if. Causality for LTI system: The output of a causal system depends only on preset and past-values  of the input. In order for a system to be causal  must not depend on  for. From equation (4.4) we see that for this to be true, all of the terms  that multiply values of  for  must be zero. put   to get or  Thus impulse response  for a causal LTI system must satisfy the condition h[n] = 0 for n < 0. If the impulse response satisfies this condition, the system is causal. For a causal system we can write          or               We say a sequence  is causal if , for n < 0. Stability for LTI system: A system is stable if every bounded input produces a bonded output. Consider  input  such that    for all n.        Taking absolute value From triangle inequality for complex numbers  we get           Using property that  Since each  we get           If the impulse response is absolutely summable, that is                                                                                                                                     (4.5) then       and  is bounded for all n, and hence system is stable. Therefore equation (4.5) is sufficient condition for system to be stable. This condition is also necessary. This is prove by showing that if condition (4.5) is violated then we can find a bounded input which produces an unbounded output. Let Let                  This is a bounded sequence                                                                       So y[0] is unbounded. Thus, the stability of a discrete time linear time invariant system is equivalent to absolute summability of the impulse response.  note:- the above all information is produced by IIT under NPtel programme
