Amplitude-stabilized transistorized low frequency oscillatorâ€
International Journal of Electronics, 1973Abstract A stable oscillator has been developed with an active frequency-selective circuit using a Wien network, adjusted below the threshold of regeneration, by providing amplitude-limited aperiodic positive feedback through a parallel path. With this method the amplitude of oscillation remains stable and can be controlled continuously while the ...

Demonstration of Low-Frequency Electrical Oscillations
American Journal of Physics, 1972An underdamped LCR circuit has been constructed which has an oscillatory period in the region of 0.5 to 5 sec. The current and emf in the circuit are measured by means of a galvanometer. The time behavior of the circuit is studied by means of a light beam chopper and sampling technique.

Low-frequency, low-distortion digital quadrature oscillator
Journal of Physics E: Scientific Instruments, 1989Digital recursive and non-recursive filtering techniques have both been exploited to build a low-frequency (0.5-50 Hz), low-distortion digital quadrature oscillator. This generator shows an amplitude constant to within 0.3% over the frequency range, and the quadrature phase error is within +or-0.05 degrees .

Ultra-Low-Frequency, Three-Phase Oscillator
Proceedings of the IRE, 1954This paper describes the design of a three-phase oscillator covering the range from 0.01 to 1,000 cycles per second. The problems peculiar to this frequency range, and their solutions, are discussed. Certain advantages inherent in three-phase operation are explained.
