Processing frequency signal involves dividing first Fourier transformed complex time signal by second, Fourier transforming resulting time signal to produce processed frequency signal

摘要

The method involves dividing the signal into at least two frequency ranges corresponding to two main components of the signal, subjecting the signal in both ranges to separate Fourier transformations to produce transformations corresponding to first and second complex time signals. The first complex time signal; is divided by the second the resulting third time signal Fourier transformed to produce the processed frequency signal. An Independent claim is also included for a distance measurement device.
