Abstract
A method for performing a fast Fourier transform. The bin spreading effect of conventional FFT methodology may be removed by a mathematical technique that relies on an incomplete replacement of the input data sequence. In the present approach this replacement is accomplished by a 'round robin' method. In this approach no window function is required and the FFT calculation proceeds after each new sample is added round robin fashion to the input sequence. The resulting output bins from the FFT show the signal evolution with time, overlapping as in the known art but by a single sample. The output of a FFT so constructed is not time invariant, but rather there is a rotation present in each output bin when viewed as an analytical signal. This rotation is predictable and hence removeable, but is also exploitable as a means to remove the bin spill over.
