D. C. Amplification and Operational Amplifiers

Abstract

In the earlier chapters, the treatment of the subject of amplification was restricted to the manipulation of a.c. signals only. This was convenient because it allowed the introduction of the essential concepts connected with amplification but kept the circuits relatively straightforward. While the amplification of just a.c. signals covers a wide variety of amplifier uses, there are a considerable number of applications in which the amplification of the d.c. component of a signal is also required.
