This is a readable introduction for those with little previous knowledge of the subject. The theme of amplification is central to many branches of electronics. Consequently there is a large and confusing array of amplifier types intended for a wide range of applications. This book describes amplifier types, how they work, their properties, advantages and disadvantages, and applications. Amplifiers are treated with the minimum of mathematics and lots of illustrations. Owen Bishop is a prolific author of books for those interested in electronics, including experimenters, students and practising engineers.
