The effects of quantisation on main-lobe width, side-lobe level and main-lobe energy for Hanning, Hamming, Blackman, sum-cosine, raised-cosine family and modified zeroth-order Bessel family data windows are presented for different word lengths. The results presented here enable the user to choose an optimum word length for a desired window. © 1979, The Institution of Electrical Engineers. All rights reserved.

A simple window that yields 6 dB improvement in the first sidelobe gain, with almost no loss in the maximum sidelobe gain, compared with that of Kaiser's near optimum zeroth-order Bessel window, is developed. The main-lobe energy of Kaiser's window is about 0·00078% more than that of the new window. The distinct advantage of the window is its very simple form similar to that of a Hamming window. © 1974, The Institution of Electrical Engineers. All rights reserved.
