I probably can't help you.
But there is one little thing I don't understand.
The code says:
So your function h(t) is equal to
But you integrate h(t*10) - you use the functionh(t)=
1 - |10*t| , |10*t| <= 1
0 , |10*t| >=1
h(t) = 1-|10*10*t|, iff |10*10*t| <= 1 and
h(t) = 0, iff |10*10*t| >=1.
Is this really the function you want to work with? I guess that is not h(t) from the quote above.
Anyway I'm not sure what I'm talking about.
