The GATE exam is one of the most competitive exams for Electronics and Communication Engineering (ECE) students. While preparing, it’s essential not just to study the GATE syllabus for ECE but to analyze GATE previous year question papers to understand topic-wise trends, weightage, and frequently asked concepts.

This post presents a topic-wise analysis of GATE exam question papers for electronics engineers to help you prioritize your preparation smartly.

Why Topic-Wise Analysis is Crucial for GATE Preparation

Identify high-weightage topics
Manage time and resources during preparation
Focus on recurring concepts asked in GATE exam question papers
Improve accuracy by targeting topics with predictable patterns
Maximize your score by mastering the most-scored subjects

Let’s break down the ECE GATE exam by topic based on the past 10 years’ GATE previous year papers.

GATE Subjects for ECE – Core Topics Overview

The GATE syllabus for electronics engineering includes the following core subjects:

Core Subjects	Avg. Weightage (Marks)
Network Theory	7 – 9
Signals and Systems	5 – 8
Electronic Devices	5 – 7
Analog Circuits	6 – 9
Digital Circuits	5 – 7
Control Systems	5 – 7
Communications	7 – 10
Electromagnetics	5 – 8
Engineering Mathematics	12 – 15
General Aptitude	15

Topic-Wise Breakdown of Major GATE Subjects for ECE

1. Network Theory

Topics: Thevenin/Norton, transient analysis, resonance, filters
Trend: Frequently asked numerical-based questions (NAT)
Strategy: Master basic formulas and solve at least 50+ problems from GATE previous year papers

2. Signals and Systems

Topics: Fourier/Laplace transforms, LTI systems, convolution
Trend: Conceptual + mathematical problems
Strategy: Practice time-domain and frequency-domain analysis with unit step/impulse inputs

3. Electronic Devices

Topics: Diodes, BJTs, MOSFETs, semiconductors
Trend: Frequently appears with theory-based conceptual MCQs
Strategy: Study device physics and I-V characteristics in depth

4. Analog Circuits

Topics: Op-Amps, amplifiers, oscillators, biasing
Trend: Regularly contributes 6–9 marks
Strategy: Focus on small-signal analysis and solve op-amp configurations thoroughly

5. Digital Circuits

Topics: Logic gates, flip-flops, FSMs, counters
Trend: Easy-to-score section if basics are strong
Strategy: Solve circuit problems involving timing diagrams and state machines

6. Control Systems

Topics: Bode plots, root locus, time/frequency response
Trend: At least 1-2 MSQs every year
Strategy: Learn to sketch root locus and Nyquist plots quickly

7. Communication Systems

Topics: AM/FM, digital modulation, noise analysis
Trend: Always one of the highest-weightage sections
Strategy: Focus on digital communication and signal-to-noise ratio problems

8. Electromagnetics

Topics: Maxwell’s equations, transmission lines, waveguides
Trend: Tougher section; but predictable types of questions
Strategy: Focus on wave propagation, boundary conditions, Smith chart
