Summary
DescriptionSinc function (both).svg |
English: Graph of both the normalized (sin(πx)/(πx)) and unnormalized (sin(x)/x) definitions of the sinc function.
These are on the same scale. The second axis is just to clarify that the zero crossings occur on multiples of pi instead of integers. Instructions: |
