Predict NowIIT Roorkee has released the GATE 2025 Electronics and Communication Engineering sylllabus at gate2025.iitr.ac.in. The GATE 2025 syllabus for EC includes 8 sections namely Engineering Mathematics, Networks, Signals and Systems, Electronic Devices, Analog Circuits, Digital Circuits, Control Systems, and Communication and Electromagnetic. GATE syllabus 2025 for ECE is divided into three sections namely Engineering Mathematics, General Aptitude, and core ECE disciplines. The core topic syllabus accounts for 72% of the exam, while Engineering Mathematics accounts for 13% and General Aptitude for 15%. Candidates must refer to the official GATE syllabus PDF for EC only for exam preparation. While studying the GATE syllabus 2025 understand the concepts well and practice numerical questions.
The GATE Electronics and Communication Engineering question paper consists of 65 questions, about 45 of which are from the syllabus of the ECE core topic. Candidates must thoroughly analyze the syllabus and GATE exam pattern 2025 and make their study plan likewise. Candidates who choose ECE as their first exam can then choose from CS, EE, IN, or PH for their second paper.
