Method for calculating spectrum of signal, involves digitizing signals and storing individual samples of digitized signal in storage unit, where Fourier transformation for samples is calculated by transformation unit

摘要

The method involves digitizing the signals (6) and storing the individual samples of the digitized signal in a storage unit. The Fourier transformation for the samples is calculated by a transformation unit as soon as the sample is stored. The Fourier transformation for the other following samples are calculated by other transformation units. Independent claims are included for the following: (1) a computer program with program code unit; (2) a computer program product; and (3) a device for calculating a spectrum of a signal.
