sigmoid function

Started by hanieh mardomi April 9, 2013
Hi, I am working on denoising of electromagnetic time series. I am going to estimate the SNR. I have two questions: what is the meaning of the smoothing parameter? what is the role of sigmoid functions on this estimation?

I do appreciate your prompt response.
Regards,

Hanieh Mardomi.
This sounds like homework. I think you should take some time to
reformulate the quesitons so they make sense - in the process I suspect
you will find your answers.

Patience, persistence, truth,
