Electronics and Communication Engineering

Wileys Acing the GATE Examination in Electronics and Communication is intended to be the complete book for those aspiring to compete in the Graduate Aptitude Test in Engineering (GATE) in Electronics and Communication discipline comprehensively covering all topics as prescribed in the syllabus in terms of study material, quick reference support material and an elaborate question bank.

One of the notable features of the book includes presentation of study material in simple and lucid language and in small sections while retaining focus on alignment of the material in accordance with the requirements of GATE examination. The study material and also the question bank have all the three important `C qualities for effective communication across to the examinees including Conciseness, Completeness and Correctness.

Another notable feature of the book is inclusion of summary of important mathematical expressions and formulae towards the end of each topic. While the study material would help examinees understand the concepts; the summary of mathematical formulations would provide to them a ready reference close to the examination day to ace the examination.

The third important feature of the book is its comprehensive question bank. The question bank is organized in three different categories namely the Solved Problems, Practice Exercise and Previous GATE Examination Questions. Solved problems contain a large number of multiple choice questions and numerical answer questions of varying complexity. Under the Practice Exercise, again there are multiple choice and numerical answer questions and their complexity is reflected by marks allotted to the questions. The third category contains questions from previous GATE examinations from 2003 onwards. Each question is followed by a complete solution.

The material presented in the book, it is divided into eight broad sections (Units) in line with the prescribed syllabus and in all, there are fifty two chapters spread out in eight different sections.

Engineering Mathematics & General Aptitude

Engineering Mathematics and General Aptitude (EM and GA) is a part of the GATE examination. Every GATE paper has a dedicated section for GA, and EM forms a part of technical section. This book can be used as resource to GATE preparation of all major engineering branches (Electronics and Communication Engineering, Electrical Engineering, Mechanical Engineering, Computer Science Engineering, Civil Engineering, Chemical Engineering and Instrumentation Engineering). It offers complete coverage of EM and GA syllabi for all these branches.
