Is there a window with both a lower side lobe level and higher side lobe roll of rate than the Blackman window - even if it is poor or useless for some other reason?

Blackmann-Harris. It's great for antialiasing as sidelobes get pushed very far down. It's transition region is far from sharp though. – Andy Walls Mar 31 '19 at 10:37

Thank you Andy. The Blackman Harris is better for side-lobe level but so much worse for roll-off. I need a window which is better against one but at least the equal for the other. Does that make sense? – Richard Mar 31 '19 at 11:52

This answer could be interesting for you. – Matt L. Mar 31 '19 at 12:23

Thanks Matt. I will check it out. Though I think the paper may not be there anymore. I will need to search for it. – Richard Mar 31 '19 at 12:33

I've updated the link; it's not a direct pdf-link, but at least you know the title and author, so you might be able to get of hold of it somewhere. – Matt L. Mar 31 '19 at 12:46

What research have you done? Wikipedia lists a whole lot of window functions. So does basically any signal processing text book. – Mar 31 '19 at 09:06

Matt; thank you again. It is early days for my testing, but that series of windows seems to be giving spectacular results. Greatly appreciated. – Richard Apr 01 '19 at 01:59
