Hi,
I'm not sure what you mean by frequency resolution
of "a Goertzel filter", but the frequency response
of the Goertzel *algorithm* is identical to the frequency
response of the discrete Fourier transform (DFT).

I did google it, but found no references. Thanks for the confirmation!

Yes.
You can verify this with several references that you can find using google
(or perhaps your question has more to it).
You were able to get a gmail account but don't like googling?? I find that
difficult to understand.

Hi,
Could someone give me the formula to calculate the frequency resolution
for a Goertzel filter? I saw somewhere that it was fs/N, where fs is
the sampling frequency and N is the block size, is this correct?
