This is a core text giving an excellent introduction to all aspects of this important and dynamic subject. The book adopts an innovative and highly tested functional approach, which emphasises the functions and objectives. The presentation is oriented to a generalised treatment of functional blocks of electronics. The approach has two major advantages : It enables students to understand basic needs and tackle them with available devices and circuits of today, at the same time giving them the background to rapidly adjust to any new advances in future ;It avoids redundancy and enables the coverage of wide range of topics in a limited time period.The book uses a generalised model for all devices like a vacuum triode, bipolar junction transistor and field effect transistor.
