Circadian oscillator period is determined around 24 hours genetically and adjusted by synchronizers such as LD cycle.
Because the two components free-ran with the same period, they were interpreted as outputs of a single circadian oscillator (Wiedenmann 1980).

Additionally, combined with the simulation results as shown in Figures 2-5, we can conclude that the designed observers have good performance under various kinds of inputs, and the input signal u(t) can affect the period of the circadian oscillator.

In most organisms, biological clockworks are governed by a master clock, referred to as the "circadian oscillator," which keeps track of time and coordinates our biological processes with the rhythm of a 24-hour cycle of day and night.
