Digital processing systems are examined for ECG and EEG signal analysis, in particular to perform filtering and spectral estimation operations. A new special digital processor is presented to perform multiple filterings and spectral estimations on several biomedical signals as ECG and EEG. Two implementation solutions are presented, having different structure and complexity. Experimental results obtained by using the digital processors for analysing EEG signals are shown for high efficiency filtering and spectral estimation. In particular the interest of using the processors to perform 2-D analysis on ECG-EEG signals is outlined.
