For presentation at National Telemetering Conference, Denver, May 1959. An analysis of a basic variable inductance modulated oscillator is presented. The transistor oscillator and the modulator are first described separately, followed by an analysis of the combined modulator-oscillator circuit. Particular emphasis is placed upon linear correspondence between oscillator frequency and modulator input stimuli. One method of obtaining this linear operation is described. Other methods requiring further investigation of the magnetic circuit are possible. Temperature stability of the circuit is discussed briefly. Some particular applications of the circuit are presented to illustrate the inherent advantages of the circuit. (auth)
