| Abstract: | Some properties of the fundamenttal interpolation function of trigonometric polynomial are discussed.When the sampling opints form a special distribution,the original periodic and band-limited signal can be reconstructed exacty by using the interpolation function of trigonometric polynomial.A interpolation formula for densing finite sampling points is given. |
