When the duration of the signal sampling is equal to zero, these effects do not occur at all. In other words, the absolutely necessary condition for their occurrence is just a nonzero value of this time. Periodicity of the sampling process plays a secondary role.}, type={Article}, title={Spectrum Aliasing Does Occur Only in Case of Non-ideal Signal Sampling}, URL={http://journals.pan.pl/Content/118868/PDF/11_3119_Borys_sk1.pdf}, doi={10.24425/ijet.2021.135947}, keywords={Signal sampling, occurrence of spectrum aliasing and folding, modelling of non-ideal signal sampling operation}, }
