Features: The book mainly consists of two parts: analog electronics and digital electronics. Analog electronics is further divided into low-frequency and high-frequency sections. The book closely aligns with the syllabus requirements, ensuring fundamental principles, knowledge, and skills while carefully selecting content to achieve a balanced depth, moderate difficulty, clear priorities, and appropriate length. The explanation of fundamental principles combines scientific rigor, modernity, and accessibility; the introduction of basic knowledge emphasizes practical applications, ensuring a solid foundation while introducing new concepts; and the training of basic skills focuses on cultivating students' abilities. Electronics is a rapidly evolving field, and this book, in addressing the relationship between the current state of electronic technology and traditional electronics, deliberately selects material that is coherent, practical, and innovative, aiming to reflect the current development of modern electronics and align with the characteristics of secondary vocational education. Electronics is a discipline that combines theory and experimentation, so a series of fundamental experiments as specified in the syllabus are arranged at the end of the book for students to use. To help students consolidate their knowledge promptly, exercises are provided at the end of each chapter for review and reference. Based on the "Secondary Vocational School Electronics Circuit Teaching Syllabus" promulgated by the Ministry of Education in 2000 and drawing on the author's extensive teaching experience, this book covers the following main topics: basic knowledge, types, and applications of semiconductor devices; basic knowledge of amplification circuits; negative feedback in amplification circuits; directly coupled amplification circuits and operational amplifiers and their applications; power amplifiers; DC power supplies; sine wave oscillators; high-frequency small-signal tuned amplifiers; high-frequency power amplifiers; amplitude modulation and demodulation; frequency mixing and multiplication; frequency modulation and demodulation; fundamentals of pulses and inverters; number systems and Boolean algebra; various logic circuits, etc. The book focuses on fundamental concepts, the intrinsic connections between knowledge, the integration of theory and practice, and post-class exercises, highlighting the basic characteristics and needs of secondary vocational education. This book is suitable for three-year students in information technology-related majors in secondary vocational schools.
