Zusammenfassung: | An EEG monitor utilizes a portable acquisition module (14) and a substantial ly stationary processing module (12). The EEG signals are acquired and converted to an oversampled stream of digital signals by a sigma-delta modulator (64) located in the data acquisition module. The signals are then filtered by a decimation filter (62) located in the processing module. Additional means are also provided to monitor the electrode leads to detect when the leads become unplugged. The monitor provides all power to the data acquisition module over a single twisted line which transmits data as well. |
