A Low-Frequency Oscillator [PDF]
Review of Scientific Instruments, 1953 A low-frequency simple-harmonic oscillator, employing a relatively new method of approach, is described. An electronic analog computer of the differential analyzer type is used to solve the differential equation of a mass-spring system. Three dc operational amplifiers perform the computation and a sinusoidal output is obtained as the solution of the ...

A synthetic low-frequency mammalian oscillator [PDF]
Nucleic Acids Research, 2010 Circadian clocks have long been known to be essential for the maintenance of physiological and behavioral processes in a variety of organisms ranging from plants to humans. Dysfunctions that subvert gene expression of oscillatory circadian-clock components may result in severe pathologies, including tumors and metabolic disorders.
