Where can I find first order interpolation? I looked at Prof.Allebach's note and textbook, I couldn't find that. If anybody knows first order interpolation, please let me know.--Park1 20:25, 22 February 2009 (UTC)
For first order interpolation, $ H_0(f)=Tsinc^2(Tf) \! $

Is it zero order? I thought we need to use$ X(f)=\sum_k(X(f-(\frac{k}{T})) $ for the first problem. --Kim415 16:56, 23 February 2009 (UTC)
