METHOD AND DEVICE FOR PERFORMING SPECTRUM ANALYSIS OF A WANTED SIGNAL OR NOISE SIGNAL

Document Type and Number:

WIPO Patent Application WO2006034763

Kind Code:

A3

Abstract:

The invention relates to a method for performing spectrum analysis of a signal in a plurality of frequency bands with respective different frequency resolutions. Said method comprises a data acquisition step (S10, S20) and a subsequent data evaluation step (S40) for every frequency band. The data acquisition step (S10, S20) and the subsequent data evaluation step (S40) proceeds cyclically and continuously for every frequency band of the spectrum analysis. The corresponding device for performing spectrum analysis of a signal cyclically stores a scanning sequence of the signal for every frequency band in one circular buffer (4_1, 4₂, 4₃, 4₄, - 4₁', 4₂', 4₃', 4₄') each. A discrete Fourier transformer (5₁, 5₂, 5₃, 5₄, - 5₁', 5₂', 5₃', 5₄') uses the cyclically stored scanning sequences to calculate the spectral values pertaining to the respective frequency band.
