Amplifier Circuits - Introduction

Amplifier applications may require control of hum, distortion, or frequency response beyond the limits of practical transformer design. Sometimes the additional performance is obtained by designing extra large transformers; this is usually an expensive procedure. Sometimes extra features can be incorporated into the transformers without marked increase in size. At other times additional circuits are used either preceding or in conjunction with the amplifier.

In this chapter several devices for obtaining special performance are considered. Transformer and amplifier design both are affected by them to a marked degree.
