Hi,
"What is Gibbs phenomenon?"
transfer function h
in time domain is infinite.
We can not implement it on DSP processor. We have to truncate it to finite lenth.
so when we truncate it. in freq domain we get the ringging at the edges.
this is called the gibbes Phenomena.
if someone have better answer then plz share to otheres.

"what is use of windowing in digital filters"
because of gibbes phenomena, we get pass band ripples & stop band attenuation.
we have to remove this, we use window function.
so, different type of window we multiply with h
