Sinc Approximation in Strip,dulus of the function sin(π./.) which we employ to get the error of Sinc approximation is both large and nearly constant on the boundary of .. We also make an assumption on the growth of . in ., which has far-reaching consequences, and which enables us to replace the infinite Sinc series by a finite one.
