FIR filter

-

hello guys,how can calculate fir filter coefficients 5hz cutoff ?
i tryed using site:
http://t-filter.appspot.com/fir/index.html
and result was:
code: [select]
-2.2204460492503132e-17
4.4408920985006264e-17
1
4.4408920985006264e-17
-2.2204460492503132e-17
is correct ?

quote
is correct ?

you didn't sampling rate was. why wouldn't 'correct' anyway?

it doesn't matter because coefficients equal 0, 0, 1, 0, 0 won't filter anything.
