There is more to circuit design than a good theoretical foundation coupled with a considerable amount of laboratory experience. While recognizing that theoretical knowledge is essential, Dr. O'Dell discusses the practical element of electronic circuit design with emphasis on learning by doing. Where do new circuit ideas come from? This is the topic of the first eight chapters, which deal with high and low frequency small signal circuits, opto-electronic circuits, digital circuits, oscillators, translinear circuits, and power amplifiers. In each chapter, one or more experimental circuits are described in detail for the reader to construct: a total of thirteen project exercises in all. The final chapter draws some conclusions about the fundamental problem of design in light of the circuits that have been dealt with in the book.
