Der durch circadiane Frequenzänderung entstehende Fehler bei der Bestimmung von Phasenverschiebungen

Summary Phase shifts () are commonly measured without considering the cue's phase position ( _s ). The normally adopted methods for measuring phase shifts give errorless results only when there is no change in period length (). Very often, however, both phase shifts and changes in period length occur together. The magnitude of the error is then a function of the magnitude of and the distance between the points of measurement and the cue's phase position. (The basic hypothesis is that is effected immediately after the cue.) Methods for calculating and eliminating the error are given.
