Spectral approach to determination of Kotelynikov's theorem application conditions
Abstract
Kotelynikov’s theorem application details are discussed for the case of signals with finite spectrum, when spectrum density at the high-frequency cutoff is nonzero. Phenomena of harmonic signal sampling when sampling frequency is twice more than the upper frequency in signal spectrum is analyzed.
