You could read 100 DSP texts without finding anything saying that an exponential averaging filter is the equivalent of an R-C filter. Thank you thank you thank you.

I have just checked back to Dr Mercer's original technical note in our archive and it seems that there was error made when transferring the equations to the blog. We will correct the post.

It should be T = h*(N-1), not T = (N-1)/h. I believe there is an error in the formula for T. It should be T = h*(N-1), not T = (N-1)/h.

I think this is one of our older articles that has been transferred from an old word processing document. Obviously, the editor (me!) failed to spot that the pi had not been transcribed correctly. It will be corrected shortly. Marco, thank you for pointing that out. I think this is one of our older articles that has been transferred from an old word processing document.
