To Our Par ents
Preface to th For almost a decade, we have been receiving tremendous responses from GAT E aspirant s for our earli GAT E Multiple Choice Quest ions, GAT E Guide, and the GAT E Cloud series. Our first book, GATE M Choice Quest ions (MCQ), was a compilat ion of objective questions and solutions for all sub jects of GA Elect ronics & Communicat ion Engineering in one book. The idea behind the book was that Gat e aspir had just completed or about to finish their last semest er to achieve his or her B.E / B.Tech need only to answering questions to crack GATE . The solutions in the book were present ed in such a manner that needs to know fundament al concepts to underst and them. We assumed t hat st udents have learned eno the fundamentals by his or her graduat ion. The book was a great success, but still ther e were a large r aspirant s who needed more preparat ory materials beyond just problems and solutions. This lar ge rat io included average st udents. Lat er, we perceived that many aspirant s couldn’t develop a good problem solving approach in their B Some of them lacked the fundament als of a subject and had difficulty underst anding simple solut ions. we have an idea to enhance our content and present two separat e books for each sub ject: one for t heor contains brief t heory, problem solving methods, fundament al concepts, and point s-t o-remember. The s is about problems, including a vast collection of problems with descript ive and step-by-st ep solut ions t be underst ood by an average student . This was the origin of GAT E Guide (t he theory book) and GAT (the problem bank) series: two books for each subject . GAT E Guide and GAT E Cloud were published subject s only. Thereafter we r eceived an immense number of emails from our readers looking for a complet e study pa for all subject s and a book that combines bot h GAT E Guide and GAT E Cloud. This encouraged us to GAT E Study P ackage (a set of 10 books: one for each subject ) for G ATE Elect ronic and Communicat i Engineering. Each book in this package is adequat e for t he purpose of qualifying GATE for an average Each book contains brief t heory, fundament al concept s, problem solving met hodology, summary of form and a solved question bank. The quest ion bank has three exercises for each chapter: 1) Theoret ical MC Numerical MCQs, and 3) Numerical Type Quest ions (based on the new GATE pat ter n). Solutions are in a descript ive and st ep-by-step manner, which are easy to understand for all aspirant s. We believe that each book of GAT E Study P ackage helps a student learn fundament al concept s and d problem solving skills for a sub ject, which are key essentials t o crack GAT E. Although we have put a v effort in preparing this book, some errors may have crept in. We shall appreciat e and great ly acknowl constr uct ive comment s, criticisms, and suggest ions from t he user s of t his book. You may write to us at [email protected] and [email protected].
Acknowledgements We would like to express our sincere thanks to all the co-authors, editors, and reviewers for t heir effor making this pr oject successful. We would also like t o thank Team NODIA for providing professional su this project through all phases of its development . At last, we express our grat itude to God and our Fa providing moral support and mot ivat ion.
