VORRICHTUNG ZUR BESTIMMUNG DES SPEKTRUMS EINES SIGNALS ÜBER EINE GROSSE FREQUENZBANDBREITE DURCH MEHRFACHABTASTUNG, UND ENTSPRECHENDES VERFAHREN

摘要

One aspect of the invention relates to a device (100) for determining the spectrum (104) of at least one signal (103) over a wide frequency band comprising: - a reception module (101) configured to receive at least a signal (103), over a wide frequency band having a maximum frequency; - a processing module (102) comprising: • a plurality of analog-digital converters (1021) in parallel configured to carry out the sampling of the received signal ( 103) at different sampling frequencies (f ₁ , f ₂ , f ₃ , f ₄ ) to obtain a plurality of sampled signals (105), the sampling frequencies (f ₁ , f ₂ , f ₃ , f ₄ ) being less than or equal to twice the maximum frequency; • a calculating unit (1022) configured to determine the spectrum (104) of the received signal (103) from the spectra of the sampled signals (105) .
