One of the most basic of all electronic circuits is the oscillator, or signal generator. Virtually all electronics systems incorporate at least one such circuit.While information on signal generators is not terribly hard to find, there has been no single source devoted to the oscillator until now.
This book tells you all you need to know about oscillator and signal generator circuits for almost any application. Over 60 practical projects are included. These circuits can be readily adapted to suit your individual requirements.
