We demonstrate that by using an adequate sampling kernel and a sampling rate greater or equal to the number of degrees of freedom per unit of time, one can uniquely reconstruct such signals. This proves a sampling theorem for a wide class of signals beyond bandlimited signals. Applications of this sampling theorem can be found in signal processing, communication systems and biological systems.[SDGs]SDG16A sampling theorem for periodic piecewise polynomial signalsjournal article10.1109/ICASSP.2001.9406942-s2.0-0034848294https://api.elsevier.com/content/abstract/scopus_id/0034848294
