图书简介
Since its original publication in 1971, this text has been a standard for signals and systems courses that emphasize probability. It provides an introduction to probability theory, statistics, random processes, and the analysis of systems with random inputs. The third edition will utilize MATLAB as a computational tool. It will be thoroughly revised to include new examples and problems, and updated to reflect the most current research and technologies. This book is intended for the junior/senior level engineering students.
