What
are the scoring Subjects of GATE ECE Exam?
GATE being a gateway to
higher studies from reputed institutes and to work in a prestigious government
organisation, it is one of the toughest exams in India. This year IIT Madras is
the organising institute for GATE 2019.

What are the scoring Subjects of GATE ECE Exam? |
It is always advisable to
have a proper strategy for preparation of this exam. There are almost 11
subjects, but few have more weightage like Mathematics, Electronic devices,
Communication system etc.
Here we are going to
provide the frequently asked topics of important subjects so that you can plan
your preparation for GATE
exam accordingly.
Important & Scoring subjects
of GATE ECE Exam 2019
1. Engineering mathematics and Aptitude (30 marks)
●
Engineering
mathematics contains 10 questions constituting a total of 15 marks and Aptitude section also has a similar pattern, that is, it also contains 10 questions
with a total of 15 marks.
●
These two segments
constitute 30% of your GATE paper; students often ignore these subjects and end up getting
lower marks.
●
You can excuse some
of the subjects like microprocessor but do not compromise with aptitude and
Mathematics.
●
One can easily score
10 plus in aptitude and 12 plus in mathematics by providing very less effort.
Book for mathematics: B.S Grewal plus previous year paper will be sufficient.
Book for aptitude: previous
year paper of all streams are
sufficient; R.S. Agarwal book for verbal and
non-verbal part is also good.
2. Network analysis (8-10 marks)
●
It is an important subject, as it helps to understand the concept
of Analog circuits and control system.
●
Important topics are: Network solution methods,
steady state and transient and steady state analysis of RLC circuit, two port
network, maximum power transfer theorem.
Book: William H. Hayt
3. Electronic devices and circuits (10-12 marks)
●
This subject should
be covered before Analog circuits as it helps to clear the basic concepts of
Analog devices.
●
Apart from having
more weightage this subject is important for electronic students.
●
Important topics are: Diffusion and drift current, P-n junction diodes and their
characteristics, solar cell ,Zener diode, BJT, MOSFET, CMOS, semiconductor
theory , diode capacitor.
Book : Semiconductor physics and
devices by Donald Neaman.
4. Analog circuits (9-11 marks)
●
As this subject has
more weightage it should be prepared thoroughly. It demands more time as some
concepts are time taking.
●
Important topics are: clipper, clamper, current
mirror circuit, DC biasing-BJT, small signal modelling of BJT & FET, BJT
amplifier, OP-amp, voltage reference circuits, feedback amplifiers, feedback
oscillator circuit, MOSFET.
Book: Sedra and Smith’s Microelectronics.
5. Communication system (10-12 marks)
●
This is one of the
most important subject for electronics and communication engineers.
●
There are some topics
which are not easy to understand so it also demands more time and effort.
●
Important topics are : Hilbert transform,
frequency and amplitude modulation, SQNR,
Superheterodyne receivers, noise, adaptive delta modulation, random
variable, FSK,PSK,QAM, power spectral density, information theory, encoding
scheme, bit error probability.
Book: Modern digital and Analog communications by B.P. LATHI.
6. Digital circuits (10-11 marks)
●
This subject has a
significant weightage but it is relatively easy to understand.
●
Questions asked from
this segment are not time taking. Generally Microprocessor is also included in
this but it has very less weightage.
●
Important topics are: Minimization of Boolean functions, Digital IC Families,
combinational circuits, multiplexer, flip-flops, counters and shift registers,
ADC, DAC, semiconductor memories.
Book: M. Morris Mano
7. Control systems (8-10 marks)
●
This subject is quite
numerical as there are many formulas but it is also one of the scoring subject
for GATE aspirants.
●
Important topics are: Block diagram, R-H
criterion time domain analysis, Nyquist plot, bode plot, root locus technique,
compensators and controllers, steady state error, state variable analysis.
Books: Automatic control systems by
Benjamin C. Kuo
8. Signal and System (7-9 marks)
●
This subject should
be done before control system and communication. It is the one of the
most important subject as it forms the base for other subjects.
●
Important topics are: Basic properties, LTI
system and their response, Fourier series and transform, pole-zero,
z-transform, filter, sampling theorem, DFT, DTFT, energy and power of digital
filter.
Books: Signal and systems by Alan V.
Oppenheim
9. Electromagnetism (8-10 marks)
●
This subject has
good weightage. It is bit tough to understand, although once understood, it is
easy to score.
●
Important topics are: Electrostatics, magnetic field, Lorentz force, uniform plane
waves, antenna characteristics, radars, optical fibre, transmission lines.
Books: Principles of electromagnetics by Matthew
N.O. Sadiku
This analysis is based on previous year
questions. To get a good rank you must have crystal clear concepts of
each and every topic (especially the important topics listed above). And it is
always advisable to make short notes of these subjects, since they are very
handy during the final phase of GATE exam preparation, i.e. revision. We hope
this analysis will be useful for your GATE ECE exam preparation.
Don’t forget to download GATE
preparation app. It provides free study notes,
quizzes, mock test, previous papers, video tutorials, and all the updates
related GATE exam.
