	The article discusses assessing the reconstruction accuracy of a signal in systems using converters with a frequency output. A Voltage-to-Frequency Converter VFC working in a dynamic state was considered. The frequency signal obtained in this manner is particularly disadvantageous from a dynamic perspective, as digital frequency processing is always a measurement of its mean value. Therefore, in dynamic states an error occurs related to the averaging and the established manner of assigning results to appropriate moments in time. Furthermore, received signal samples are nonuniformly distributed over time. A simulation algorithm was developed that makes it possible to obtain digital samples of instantaneous values of a frequency signal from a VFC for the input signal provided in analytical form. The results of conducted simulation studies are presented. The influence of input signal parameters on the obtained Effective Number of Bits ENOB value of the tested converter has been analyzed.
