TLDR
A set of windows whose normalized half main-lobe widths fall between those of rectangular and the Hanning or Hamming windows, is proposed, and is compared with Kaiser's near-optimum zeroth- order Bessel and first-order Bessel windows.Abstract:
A set of windows whose normalized half main-lobe widths fall between those of rectangular and the Hanning or Hamming windows, is proposed. These windows are compared with Kaiser's near-optimum zeroth-order Bessel and first-order Bessel windows. The results show that the new windows compare very favourably with Kaiser's windows. The distinct advantage of the windows is their very simple form, similar to that of a Hamming window. As an example of the use of these windows, an estimate of the log power spectrum of a signal consisting of two sinusoidal tones of unequal amplitudes is considered and compared with the estimates using other windows.read more

TL;DR: A new window family is introduced, whose normalised half mainlobe width falls between those of rectangular and Hamming windows, and is compared with a Kaiser-Bessel window, and a tanh window.

On the use of windows for harmonic analysis with the discrete Fourier transform
TL;DR: A comprehensive catalog of data windows along with their significant performance parameters from which the different windows can be compared is included, and an example demonstrates the use and value of windows to resolve closely spaced harmonic signals characterized by large differences in amplitude.

TL;DR: In this article, a comparison of the well-known and novel windows in terms of their frequency domain properties is given, and it is concluded that Kaiser, modified Kaiser, Tukey, and three-coefficient window families appear to be the best of the known windows of 6, 12, and 18 dB/oct decay rates.

On the use of asymmetric windows for reducing the time delay in real-time spectral analysis
TL;DR: The idea of asymmetric windowing as a way of reducing time delay in spectral analysis is explored and it is shown that it is possible to reduce the time delay up to about 25% of the analysis window size.
