In the link sigwin.chebwin it has given frequency domain response equation I think. I need time-domain equation. Something like given in the literature like this paper this paper, or this paper which represented it respectively as
Is it the same equation generated by sigwin.chebwin?
Also shown that signwin.chebwin is not recommended. Use Chebwin. But in the documentation of chebwin it is shown that it generates Chbyshev window. How to get the Dolph-Chebychev window equation.
Please do suggest.

Hi Palguna Gopireddy,
It is my understanding that you are expecting to get Dolph-Chebychev window equation that is in accordance to the IEEE papers that you mentioned.
You can refer the given File Exchange contribution - Window Utilities in which 'sdchebwin - Dolph-Chebyshev window using Saramaki's formulas' might help with your requirement of a time-domain equation. 'sdchebwin'is in accordance to the IEEE paper which has a common author as the research paper you shared (Tapio Saramaki).
Hope you find it helpful.
