Signals and Systems, Volume 2 : In Discrete Time

The book begins by introducing signals and systems, and then discusses Time-Domain analysis and Frequency-Domain analysis for Continuous-Time systems. It also covers Z-transform, state-space analysis and system synthesis. The author provides abundant examples and exercises to facilitate learning, preparing students for subsequent courses on circuit analysis and communication theory.

The Signals and Systems course is an important professional fundamental course for undergraduates majoring in electronics, information and communication, and control, etc. It has a profound influence on the cultivation of students’ overall abilities, such as independent learning, scientific thinking in problem solving, practical skills, etc. The course is not only compulsory for undergraduates but also necessary for postgraduate entrance examination in related majors. The course plays a critical role in undergraduate education, and it is the theoretical foundation for information theory and mastering information technology. It is even regarded as the key to opening the door to information science in the twenty-first century.

This book is Volume 2 of “Signals and Systems” written by Weigang Zhang and published by De Gruyter Press and Tsinghua University Press for the undergraduate course “Signals and Systems”. The problems about discrete time signals and systems analysis in the time domain and the z-domain and the state-space analysis of systems were mentioned in this volume. At the end of the volume, several examples in communication systems were given, which relate to signals and systems analysis theories and methods.
