Classes starting with E
(rhythm) An oscillating system capable of self sustained oscillations.
Coupling of an endogenous rhythm to a Zeitgeber with the result that both oscillations have the same frequency. Possible only within limited ranges of frequencies. In entrainment, by coupling the phase of the endogenous rhythm is affected, in contrast to ìmaskingî.
(rhythm) An oscillating system not capable of self sustained oscillations, but passively driven by external factors.
