GATE EC Previous Year Questions & Study Resources
GATE Electronics and Communication Engineering (EC)
1,365 solved GATE EC questions from 2014–2026, each with the official answer and a step-by-step solution. Solving past papers is the highest-signal preparation there is: it teaches the real difficulty level, the recurring topics, and the time pressure of the actual exam.

GATE EC subject-wise PYQs
Choose a subject to revise one area at a time. Subject tags can overlap; these question counts are not marks weightage.
Continue learning with Success Tracker
Build on your GATE EC PYQ revision
Reading a solution is a useful start. In Success Tracker, you can attempt questions yourself, review mistakes and return to the topics that need another pass.
- PYQs with solutions
- Attempt available previous-year questions, then compare your reasoning with the worked solution. Coverage varies by stream.
- Practice that adapts
- Choose a topic, work on weaker areas and bookmark questions to revisit. Your attempts feed your progress tracking.
- AI doubt support
- Ask follow-up questions about a step or concept while practising, instead of stopping at the final answer.
Unlimited practice is available on eligible plans. Free practice and AI usage have limits; check the current plan allowances before choosing.

Learn the concept, then solve the PYQs
Start with the available GATE EC revision companions: Engineering Mathematics, General Aptitude, Electronic Devices, Digital Circuits, Signals & Systems, Communications, Analog Circuits, Network Theory, Control Systems, Electromagnetics. Each combines concept notes, mistakes to avoid, an original worked example, a self-check and free further reading with the subject’s PYQs. No account is needed to read them.
Engineering Mathematics: verify conditions before applying a result
State the domain, convergence, or smoothness condition a formula requires before substituting. These selected foundations connect linear algebra, calculus, differential equations, complex analysis, and probability as they appear in the GATE EC syllabus. Each area needs its own deeper study.
Read notes and solve questionsGeneral Aptitude: read the claim, then test it
Separate what is stated from what is inferred. Verbal reasoning depends on the passage's own claims; quantitative reasoning depends on a stated relationship. These selected foundations connect reading comprehension, data interpretation, and basic arithmetic reasoning. They are not a substitute for broader practice.
Read notes and solve questionsElectronic Devices: identify the region before applying the model
Determine the operating region of each device before writing its current-voltage relationship. These selected foundations connect semiconductor physics, diode characteristics, BJT modes, and MOSFET regions. The original exercises use ideal device models for learning, not fabrication guidance.
Read notes and solve questionsDigital Circuits: trace values through gates and state
Separate combinational output (determined by present inputs) from sequential output (determined by present inputs and stored state). These selected foundations connect Boolean algebra, gate-level design, and finite-state machines. Verify each simplification by evaluating input combinations.
Read notes and solve questionsSignals & Systems: preserve indices and test system properties
Connect continuous-time signals, discrete-time signals, and LTI systems using explicit coordinates and assumptions. These selected notes emphasize convolution and frequency interpretation, not a complete syllabus. The original calculations use abstract signals without physical implementation.
Read notes and solve questionsCommunications: separate the signal model from the channel
Define the message signal, modulation scheme, and channel model before computing bandwidth or error probability. These selected foundations connect analog and digital modulation, sampling, and information theory. The original exercises use ideal mathematical models.
Read notes and solve questionsAnalog Circuits: validate the operating region before the gain
These selected foundations connect device models, amplifier bias, and feedback. Separate DC bias from incremental signals before calculating gain. The original examples are symbolic DC problems with rail-limited ideal op-amps, not electrical construction guidance.
Read notes and solve questionsNetwork Theory: label terminals, sources, and time regimes
These selected foundations connect circuit theorems, transient and AC analysis, and two-port descriptions. Distinguish DC equilibrium, switching transients, and sinusoidal steady state. The original ideal-element problems are symbolic educational exercises, not electrical construction instructions.
Read notes and solve questionsControl Systems: check stability before evaluating performance
Determine whether a system is stable before computing steady-state error or bandwidth. These selected foundations connect transfer functions, time-domain response, frequency-domain methods, and state-space representations. The original exercises use idealized linear models.
Read notes and solve questionsElectromagnetics: identify the symmetry before choosing a law
Use the field symmetry to select Gauss's law, Ampère's law, or a direct integral, then verify boundary conditions. These selected foundations connect electrostatics, magnetostatics, and wave propagation. The original exercises use ideal geometries and lossless media.
Read notes and solve questionsA repeatable PYQ revision routine
- Attempt a question before reading its solution. Write down your assumptions and reasoning, not just the answer.
- Compare the reasoning. Classify a miss as a concept gap, a calculation error or a misread condition.
- Use the revision notes to repair the gap, then attempt a different question from the same subject.
- Reattempt the missed question later without the solution. Use a complete paper to check pacing after topic revision.
