WebbOctave-Forge is a collection of packages providing extra functionality for GNU Octave. WebbThe sinc function is used in various signal processing applications, including in anti-aliasing, in the construction of a Lanczos resampling filter, and in interpolation. For bandlimited interpolation of discrete-time signals, the ideal interpolation kernel is proportional to the sinc function.
