GATE 2021 : 10 answered questions


Ques. How did you prepare for signal and systems for the GATE?

● Top Answer By Aniket Ranjan on 08 Jan 21

Ans. While there is no set rule for preparing for the signal and systems module of GATE, there are usually two routes or a combination of both that is advised to students. You can either focus on theoretical books and samples like Julius O Smith to study or you can follow online learning tutorials like Edx open software to get clear concepts. Preparation Tips: To begin with, students must always have an in-depth understanding of the foundation subjects. This means starting your study module from between will only cause you to have unclear concepts. It is an exceptionally important topic, and hence students must focus on understanding the concept of Impulse Response and Convolution. Learn the impact of shifting and scaling operations on the waveform to understand continuous and discrete-time signals. For problem-solving questions, it is important to focus on Properties of transforms, analysis and synthesis equations, and common transform pairs. If you have the time, try to learn about all the properties since it can be asked as a direct question. The Fourier transform and Laplace transform are two very important concepts that can contribute to higher marks because of its direct approach. Students must also study the final value and initial value theorem with stability verification. The idea of stability and causality in Z Transform and Laplace can be very scoring if system properties need to be identified from the pole-zero plot. Students can also practice drawing two separate types of waveforms keeping sampling frequency and Nyquist frequency in mind. The concepts of Nyquist Rate, Nyquist Frequency, and Band-Pass sampling theorem are all incredibly important. Study Material: For practicing and learning materials students can find the following. Main Text Book by Schaum series Signal Systems by Prof SC Dutta Roy or Oppenheim Kreatryx Practice Question booklets GATE questions from previous years Signals & Systems has the highest weightage of marks and so it can easily become a high-scoring subject if prepared well. Practicing a large number of problems while understanding core concepts is mandatory to get a score in the subject. Keeping these points in mind will surely help students in getting a good score in signals and systems for GATE.Read more

Ques. Can I get admissions to IIT’s without GATE?

● Top Answer By Bhavya Rawal on 08 Jan 21

Ans. GATE is an online competitive exam conducted for qualification to ME, MTech, or P.hD. programs for admissions in top institutions like IIT, NIT, IIIT, and other institutes in India. It is conducted on the behalf of NCB and the Ministry of Human Resource and Development, Government of India. For admissions in any of the IIT branches, students have a few other alternatives to get qualified than just appearing for GATE. Admissions can be given under the given circumstances: Eligibility: Students who have graduated in Engineering with a degree from IIT are exempted from appearing for GATE examinations and can directly apply and appear for a written test. Students who have completed their BTech degree from another university but have a minimum CGPA of 8.0 and above consistently in the last two years, need not appear for GATE. These students can directly appear for the written test and personal interview round. Institute: Students who have an Engineering degree from a Centrally Funded Technical Institute (CFTI) and have a high CGPA of above 8.0 can be exempted from appearing for GATE. The criteria are only accessible within certain campuses of IIT depending upon the branch of study chosen. Sponsored category: Some IIT campuses also offer direct admissions under the sponsored category for top industry personnel or for individuals in academia. For high-level academicians, admissions to Master’s or Ph.D. programs can be done under the Quality Improvement Program (QIP). Integrated Course: For students who do not want to appear for GATE but are still looking at a master’s degree from IIT, you can opt for the 5-year integrated program (MTech+PhD). In order to be eligible for admissions to this program, students must mandatorily have a CGPA of 7.5 and above in a relevant field of Engineering. Furthermore, students who have more than 2 years of work experience and are working for companies that have any links with IIT and sponsor students for master’s courses can be exempted from providing GATE scores for admissions.Read more

Ques. Can I prepare for GATE and UPSC simultaneously?

● Top Answer By Ayan Dey on 04 Dec 20

Ans. GATE and UPSC exams have a lot of similarities. Both these exams are high up on the difficulty level and are attempted by graduates. Questions in GATE are based on problem-solving and questions in UPSC are meant to test the discipline of a candidate. However, if you are smart in choosing your optional subjects for UPSC & GATE, then studying the same subjects can help you in both of these exams. This is especially true if you are preparing for the Engineering Services Exam (ESE) in UPSC. Similarities in Syllabus: For technical subjects, the ESE and GATE syllabus are almost similar (80-90%). Even in the non-technical part the Engineering Aptitude and Engineering Mathematics parts are the same for ESE and GATE. You only need to prepare for general study subjects like Current Affairs, Ethics, Project Management, Basic Energy and Environment, Information and Communication Technologies, Standard and Quality, Material Science, and Design-drawing for ESE. It may seem like a lot of subjects, but these are quite interesting and take less time to cover. The study material of these subjects has hardly 150-200 pages including practice papers. Preparing for GATE & UPSC simultaneously is difficult, but not impossible. Through a clever selection of optional subjects and hard work, you can prepare efficiently to tackle both these exams.Read more
