What Is Gibb’s Phenomenon?

1.	What Is Gibb’s Phenomenon?
Answer» One possible way of finding an FIR FILTER that approximates H(EJW) would be to truncate the infinite Fourier series at n=±(N-1/2).Direct truncation of the series will lead to fixed percentage overshoots and undershoots before and after an approximated discontinuity in the frequency response.
