WebThe Dolph-Chebyshev window (a.k.a Chebyshev window) is used in signal processing. It is optimal in that it has a minimum main-lobe width for a given side-lobe attenutation. Another property of the Chebyshev window is that it is equi-ripple, i.e. the side-lobe height is the same at all frequencies. The Dolph-Chebyshev Window §
