Wien bridge oscillator

Experiments on Wien-bridge oscillators showed such anomalous fluctuations to exhibit a variance proportional — where /3 is the reaction factor and the corresponding threshold value. The relaxation time... [Pg.451]

The time behavior as experimentally detected on a Wien-bridge oscillator has been accounted for by using the theories of Kubo et al. ... [Pg.451]

Horn et al. simulated phase transitions of the first and second kind, and a three-critical point, via a Wien-bridge oscillator. Such behavior is fairly well accounted for by the Landau theory except for very close to the critical point. Furthermore, Horn et al. observed that the phase of their oscillator had a... [Pg.451]
