On the use of the I0-sinh window for spectrum analysis

Closed form expressions for main-lobe width, modified main-lobe width, and relative sidelobe amplitude are given for the
I_{0}- \sinh
window function. These formulas facilitate exploring the tradeoff between record length, spectral resolution, and leakage in digital spectrum analysis. An especially simple empirical approximation relating main-lobe width and relative sidelobe amplitude is given.
