EN The short-term flicker severity indicator Pst is the output signal of a so-called flickermeter system that makes it possible to estimate the obnoxiousness of flicker caused by voltage fluctuations. The processing characteristic of the flickermeter is based on a limited set of standard points. In this paper, the results of the analysis of a simplified model of this system are presented. The model consists of a set of three equations that interpolate and extrapolate the transformation characteristic for modulation with a sinusoidal modulating signal. The proposed deterministic model makes it easier to understand the processing being performed in the examined signal chain.
