Abstract: The properties of sinc approximations are considered. Previously used classical sinc-approximations provide poor approximation quality, while a new operator generalizing sinc approximations yields better results. The numerical implementation of an experiment is presented in plots.
Key words: sinc approximation, interpolation operator, approximation of continuous functions, numerical experiment, approach by operator.
