## Introduction

Electronic engineering is an electrical engineering discipline that utilizes nonlinear and active electrical components (such as semiconductor devices, especially transistors, diodes, and integrated circuits) to design electronic circuits, devices, VLSI devices, and their systems. The discipline typically also designs passive electrical components, usually based on printed circuit boards. This article will give you complete information regarding the GATE Electronics and Communications Engineering Syllabus 2023.
