Abstract

Kinds of adjustable windows are flexibly applied in digital filter design and spectral analysis. But general description of adjustable windows for any window length are always deficient in time domain and frequency domian. Moreover, there lacks quantitative comparison of spectral characteristics among adjustable windows. In this paper, analytic expressions that suit for any window length were utilized to describe adjustable windows, including the Kaiser, Cosh, Dolph-Chebyshev, Saramäki and other ultraspherical windows. The spectral characteristics of adjustable windows were obtained through numerical computation, and their curves were numerically fitted with simple functions about adjustable parameters. The relative deviations between the computed curves and the fitted ones are normally less than 7 percent. Finally, detail comparison of spectral characteristics among adjustable windows were performed from multi-sides. It shows that the Saramäki window has better overall performance than other adjustable windows by comparing spectral characteristics.
