Résumé

The spectral analysis of ADC digital data has traditionally been done with discrete Fourier transform. This method imposes restrictions to optimize the results: one of these is coherent sampling. Recently, some filter structures have been used for the spectral analysis of sinusoidal signal corrupted by harmonics and noise. In this paper, we present a filter bank structure used for decomposition of a signal into his main spectral components. The main application examined is ADC spectral parameters extraction (SINAD, SNR, THD) with non coherent sampling. Computer simulations are used to demonstrate the performance of the proposed filter structure.
