Fundamentals of oscillator design

The primary goal of the designer of every technical system is to achieve a certain functionality. At the highest level in the design of this technical system, the designer is not interested in the technology that is used to implement this functionality. It could as well be implemented as a mechanical system as an electronic system, or as a chemical system. At the highest level, the behavior of the system can be described as a set of mathematical equations. The actual design of the system comes down to the implementation of these equations using one technology or another.
