    About this ebook

    During the long career of the author as a writer of technical articles and books, he have on several occasions addressed the theme "collection of circuits", also including information. Thus, previously, addressing this theme, he published the series "Circuits and Information" (7 volumes) and "Circuits and Solutions" (5 volumes) containing hundreds of useful circuits and technical information of all kinds. The series has run out, time has passed, but readers still charge us something similar updated and that can still be used in projects of all kinds. In fact, basic circuits using ordinary discrete components, from transistors to integrated circuits, are still widely used as simple solutions for immediate problems, part of more advanced projects and even for didactic purposes, at the request of a teacher who needs an application for a theory. So, he is back with this series, but with a differentiated structure, new projects and a new approach. The difference in approach will be to divide the various volumes of the series by themes, we will have audio circuits,such as amplifiers, preamplifiier, mixers, etc. In his stock of circuits, collected from all possible sources, he already have more than 12,000 of them, many of which can be accessed in a dispersed way in the site of the author. The advantage of having these circuits organized in volumes, besides access anywhere, is in the easy location of a circuit. The information, on the other hand, will be added to the circuits, with internal links, which is only possible in a digital publication. Most of these circuits, collected in publications that, in some cases, may not be very current, receive a special treatment with comments, suggestions and updates that make possible its execution even in our days.

      Introduction

      The term Circuit Bench was used many times along our long career as a technical writer of books and articles all over the world. So, prior this serie, based in this theme we had published two book collections in Brazil: Circuits and Informations (Circuitos e Informações) – 7 volumes and Circuits and Solutions (Circuitos e Soluções – 5 volumes). These collections gathered hundreds of circuits and useful information about components, design, formulas and tables. The series are out of print now but our readers are asking us for something like that to be used in electronic projects of all kind. In fact, basic circuits using common discrete componentes such as transistors and Ics are today used as fast solutions for imediat problems, part of more advanced projects, as shields for microcontrollers and with didatic purposes for a school work or demonstration. So, we returned with this serie, but with a different approach and new projects. The different approach is the division of the volumes by themes. So, in this second volume the circuits gathered had audio as main subject. In fact, since we have in our collection more than 12 000 circuits many, of then can be found in our site, but following no organization. The advantage for the reader is that in this book the circuits are organized by
