Dolph-Chebyshev Window DefinitionLet denote the desired window length. Then the zero-phase Dolph-Chebyshev window is defined in the frequency domain by 
where is defined by the desired ripple specification:
where is the ``main lobe edge frequency'' defined by
Expanding in terms of complex exponentials yields
where . Thus, the coefficients give the length Dolph-Chebyshev window in zero-phase form.
