Abstract :
The narrow main lobe widths of Dolph-Chebyshev (1946) spectral windows can be approximated to within about 4%, with sidelobe depression to at least -98 dB, by windows defined with four Fourier series coefficients. Two windows may be particularly attractive, the opt59 and opt71 windows, since the true value of the fourth coefficient is zero
