Electronics & Communication Engineering(ECE) is a versatile branch in the field of engineering. The term "Electronics and Communication Engineering" denotes a broad spectrum engineering stream that integrates many sub streams such as analog electronics, digital electronics, consumer electronics, embedded systems, communication systems and power electronics. The discipline deals with the implementation of principles, applications and algorithms developed within related fields like control systems, radio engineering, telecommunications, computer engineering, instrumentation engineering, signal processing, systems engineering, electric power control, robotics, and many others. ECE handles electronic devices, circuits, communication equipments like transmitter, receiver, integrated circuits (IC).
The dynamic branch not only deals with electronic devices but also software interfaces.
It strives to broaden the knowledge and skills of the students on the basic concepts and theories that will equip them in their professional work involving analysis, systems implementation, operation, production, and maintenance of the various applications in the field of Electronics and Communications Engineering.
A combined competitive examination is conducted by the Union Public Services Commission (UPSC) for recruitment to the Indian Engineering Services. The Examination constitutes of a written examination followed by an interview for personality test.
Every IES exam is divided into two sections -
Paper I & Paper II .
While paper I remains common for all the branches/streams of engineering, the paper II is specialised with respect to the branch of engineering students.
In this case, it is Electronics and Communication Engineering.
Indian Engineering Services(IES) include technical and managerial services for government of India. The pay scale of Indian Engineering Services is as high as the pay scale of IAS officers. After 7th pay commission, an IES officer with their esteemed cadre receives more benefits along with high salary and varied allowances and benefits.

The topics are meticulously curated by our proficient and well-experienced senior Professors/Lecturers of Vani Institute across the country identifying the critical topics for subjects from IES assessment perspective. Based on their needs or requirement, an aspirant can choose any suitable package:
This module is designed to help you solve the tests for Online Preparation on IES 2019
ECE and understand the concepts associated with the questions provided. AspireBuzz follows the principle of Stimulation Based Learning, an unique interactive module, where the aim is to stimulate our conceptual analysis and reach to the solution on our
own rather than the direct answer approach. Each question in this test series is accompanied by three videos:
This package is ideal for students who are already preparing for the UES and are looking towards further robust enhancement in the preparation for IES 2019 ECE through online preparation mode. The package comes along with multiple questions for the students to perform and solve. Each question is accompanied with a solution. The solutions available are in a relevant text format in this and so does not contain any videos.
You can very well anytime, anywhere register for a free demo/trial package with our learning platform AspireBuzz and let your journey for Online Preparation of IES 2019 ECE begin.
