  • Abstract
    Unless inconveniently high sampling rates are used, the fast-Fourier-transform (f.f.t.) algorithm, being a trapezoidal integration rule, gives errors in the tails of spectra. A transform with a square-wave kernel, which can be evaluated accurately in a simple manner, is proposed to complement the f.f.t. An example involving measured data is included.
