Abstract : A Fourier analysis is performed on 'corrected' HERO turntable data. Specified harmonics may be plotted, with the original data, in polar coordinates, in order that the several harmonics can be compared with the original data. The option is provided for setting any combination of Fourier constants equal to zero, and plotting the resulting polynomial. 'Corrected' data have undergone conversion from deflections to currents, and have been normalized to the maximum at the base of the radiating antenna. (Author)
