Systemization of Sinusoidal Feedback Oscillators (A Teaching Aid)

This paper presents a systematic procedure for the analysis of sinusoidal feedback oscillators. The approach is a unified one in the sense that tubes and transistors are considered simultaneously and in that the various oscillators are categorized into families for purposes of analysis. Emphasis is placed on relationships characteristic of sinusoidal feedback oscillators in order to satisfy the teaching need for a precise comprehensive treatment of such circuits. Too often the authors of electronics textbooks stress the analysis of specific oscillatory circuits, with the result that the fundamental principles involved are largely suppressed.
