The most famous result in this direction is the Whittaker-Shannon-Kotel'nikov formula, which allows to reconstruct bandlimited signals (i.e., signals containing no frequencies beyond a critical value ωc) from an equidistant sequence of samples whose spacing depends on ωc.application/pdfeng© Elsevierresearch articleMatemáticas10.1016/S1076-5670(02)80042-8open access
