Features: The second edition of Discrete-Time Signal Processing retains the style of the th edition, but considering that "Digital Signal Processing" courses have become widely offered at the undergraduate level at the end of the 20th century and the beginning of the new millennium, the authors believed that as a textbook, it should not aim to "cover" all aspects of the development of the discipline, but rather to reveal the fundamental knowledge, basic theories, and basic methods of a subject, thereby enhancing the problem-solving skills of students and engineers. The authors have removed some content not essential for the undergraduate level, such as the cepstrum and homomorphic signal processing, which has been moved from the main text to the exercises. At the same time, considering the importance of multi-rate signal processing in oversampling A/D and D/A conversion and digital filter implementation in signal processing, this part of the content has been expanded. For example, the cosine transform, which plays a significant role in data compression, has been introduced into the textbook. These additions and deletions in the content allow the textbook to elaborate on classic material while continuously introducing new concepts, reflecting the rationality, scientificity, and modernity of the textbook. Another major feature of the second edition is its practicality. "Digital Signal Processing" is a highly practical course, and Oppenheim has maintained the style of writing books in recent years, leaving readers with a wealth of exercises. Some of the exercises are derived from literature and are of considerable difficulty. This edition has expanded the number of exercises from th edition's 371 to 588, and the number of examples from 113 to 137; at the same time, the exercises are divided into three levels: basic problems (with answers), in-depth problems, and extended problems. These exercises are extremely helpful for deeply understanding the textbook content, consolidating basic concepts, and cultivating the ability to analyze and solve problems. Learning digital signal processing cannot be separated from hands-on practice. Although this textbook does not contain specific laboratory guides, as stated in the preface, "Many of the exercises in this book can be easily transformed into computer-based practice problems," and specific approaches are pointed out. In summary, this book is a significant work by Oppenheim in the field of digital signal processing textbooks. It is clear in concept, rigorous in explanation, well-organized in content, and rich in examples and exercises, making it an excellent foundational textbook. Although the above textbooks have corresponding Chinese translations, it is necessary to understand the authors' thought process and clarify concepts more accurately by studying the original text, allowing the Chinese and English versions to complement each other, experience its essence, and apply it in practice.
... Professor Alan V. Oppenheim of the Massachusetts Institute of Technology is a leading figure in the field of signal processing. His several works on signals and signal processing have become classic and renowned worldwide. His th edition work, Digital Signal Processing (1975 edition), is considered a classic textbook in this field. It systematically summarizes the fundamental theories, concepts, and principles of digital signal processing. The book is clear in concept, strong in logic, rigorous in reasoning, and is an excellent textbook for digital signal processing. Some universities in China began to offer digital signal processing courses in the late 1970s and early 1980s, during which Oppenheim himself came to China to lecture at Tsinghua University and other institutions. His lecture videos were widely circulated in China. Subsequently, most digital signal processing textbooks published in China were written based on the framework of Oppenheim's works. With the development of the times, as an emerging discipline, new theories, concepts, algorithms, and applications related to digital signal processing have continuously emerged. After twenty years, to adapt to the development of the times and meet new demands for teaching content, Oppenheim published the book Discrete-Time Signal Processing (the th edition) in 1989. This book made significant adjustments based on the original, focusing on strengthening and updating fundamental content, providing more detailed discussions on some newly developed foundational topics, clarifying basic concepts, organizing content more reasonably, and greatly increasing examples and exercises. In 1999, Oppenheim made necessary revisions to Discrete-Time Signal Processing, releasing it in the second edition format. The second edition retains the style of the th edition, but considering that at the end of the 20th century and the beginning of the new millennium, "Digital Signal Processing" courses had become widely offered at the undergraduate level, the authors believed that as a textbook, it should not aim to "cover" all aspects of the development of the discipline, but rather to reveal the fundamental knowledge, basic theories, and basic methods of a subject, thereby enhancing the problem-solving skills of students and engineers.
