Signals and systems
About the Book : The Third Edition of this well-received text continues to provide coherent and comprehensive coverage of signals and systems. It is designed for undergraduate students of electronics and communication engineering, telecommunication engineering, electronics and instrumentation engineering, and electrical and electronics engineering. The book will also be useful to AMIE and IETE students. Written with student-centred, pedagogically driven approach, the text provides a self-contained introduction to the theory of signals and systems. This book looks at the concepts of systems, and also examines signals and the way that signals interact with physical systems. It covers topics ranging from basic signals and systems to signal analysis, properties of continuous-time Fourier transforms including Fourier transforms of standard signals, signal transmission through linear systems, relation between convolution and correlation of signals, sampling theorems and techniques, and transform analysis of LTI systems. All the solved and unsolved problems in this book are designed to illustrate the topics in a clear way. Contents : Preface Preface to the First Edition 1. Signals 2. Systems 3. Signal Analysis 4.

Probability Theory and stochastic processes
This comprehensive text on switching theory and logic design is designed for the undergraduate students of electronics and communication engineering, electrical and electronics engineering, electronics and instrumentation engineering, telecommunication engineering, computer science and engineering, and information technology. It will also be useful to AMIE, IETE and diploma students. Written in a student-friendly style, this book, now in its Second Edition, provides an in-depth knowledge of switching theory and the design techniques of digital circuits. Striking a balance between theory and practice, it covers topics ranging from number systems, binary codes, logic gates and Boolean algebra to minimization using K-maps and tabular method, design of combinational logic circuits, synchronous and asynchronous sequential circuits, and algorithmic state machines. The book discusses threshold gates and programmable logic devices (PLDs). In addition, it elaborates on flip-flops and shift registers. Each chapter includes several fully worked-out examples so that the students get a thorough grounding in related design concepts. Short questions with answers, review questions, fill in the blanks, multiple choice questions and problems are provided at the end of each chapter. These help the students test their level of understanding of the subject and prepare for examinations confidently. NEW TO THIS EDITION • VHDL programs at the end of each chapter • Complete answers with figures • Several new problems with answers

GATE 2024 : COMPUTER SCIENCE AND IT ENGINEERING PREVIOUS SOLVED PAPERS
Computer science is a discipline that extents theory and practice. It needs thinking both in abstract terms and in concrete terms. The practical side of computing can be seen everywhere. Computer science also has strong connections to other disciplines. Many problems in science, engineering, health care, business and other areas can be solved efficiently with computers, but finding a solution requires both computer science expertise and knowledge of particular application domain. Computer science has a wide range of spheres. These embrace computer architecture, software systems, graphics, artificial intelligence, computational science and software engineering. Drawing from a common core of computer science knowledge, each speciality area emphases on particular challenges. A Handbook on Computer Science encompasses all the formulae and important theoretical aspects of computer science, with appropriate diagrams, whenever it is appropriate. An extensive coverage of key points for additional information is also given. This handbook covers all essential concepts and terms in computer science.
