The GATE examination pattern has undergone several changes over the years—sometimes apparent and sometimes subtle. It is bound to continue to do so with changing technological environment. Apart from giving the aspirant a chance to pursue M.Tech. from institutions like the IITs /NITs, a good GATE score can be highly instrumental in landing the candidate a plush public sector job since many PSUs are recruiting graduate engineers on the basis of their performance in GATE. Topic-wise Tests GATE Electronics and Communication Engineering acts as a one-stop assessment tool for all GATE aspirants. The book consists of topic-wise tests on (1) General Aptitude, (2) Engineering Mathematics, and (3) Electronics and Communication Engineering. Five full-length mock tests based on latest GATE pattern are provide at the end of the book, which will help students to check their level of preparation for GATE exam. As a result, this book would serve as an effective tool for GATE aspirant to crack the examination. Highlights • Includes (1900+) problems for practice • Includes (53) topic-wise tests based on latest GATE pattern. • Detailed solutions given for each test • Includes tests on General Aptitude and Engineering Mathematics • Includes 5 full-length mock tests based on latest GATE pattern Despite of our best efforts, some errors may have inadvertently crept into the book. Constructive comments and suggestions to further improve the book are welcome and shall be acknowledged gratefully.
