The theory of probability, applied extensively in all fields of engineering and physical sciences to model situations and outcomes, finds usage in fields as varied as social and behavioural sciences, biology, economics, management and business studies as well. This book, written to cater to an undergraduate engineering curriculum, explains the concepts and the mathematics of probability and stochastic processes to enable a student to solve practical problems with confidence. It covers probability axioms, conditional probability, special distributions, random variables, expectations, generating functions, operations on random variables, random processes and their temporal and structural characteristics and response of linear systems to random signals. Several solved examples illustrating the application of key concepts have been included in each chapter. This, together with the generous number of chapter-end exercises of varied levels of difficulty makes this book invaluable as a textbook on the subject.

Pradip Kumar Ghosh is professor of electronics and communications engineering at the Mody Institute of Technology and Science (Deemed University), Sikar, Rajasthan. He obtained his B Tech and M Tech degrees in radio physics and electronics from Calcutta University in 1989 and 1991 respectively, and his Ph.D. (Tech) from the same university in 1997 with a fellowship from the Council of Scientific and Industrial Research (CSIR), New Delhi. Dr Ghosh has about twelve years of teaching experience, having taught at the National Institute of Science and Technology (NIST), Berhampur, Orissa, St. Xavier''s College, Kolkata and Murshidabad College of Engineering and Technology, Berhampur, West Bengal, prior to his current assignment. He is the author of Principles of Electronic Communications: Analog and Digital, published by Universities Press.
