Abstract :
The present paper deals in the first part with a presentation of the sampling theorem in two known forms, referring to the bandwidth and to maximum/highest frequency of spectrum. In the second part of the paper, a practical mathematical algorithm, as an undersampling method is presented. Characteristics and experimental results are finally analyzed.
