Working theory
The system can transform biomedical signal into electric signal through signal detection and reprocess Module, at the same time preprocess interference suppression, signal filtering and amplification and so on.Then it will conduct a computational analysis to the parameters after the sampling and quantification through data extraction and Preprocess Module. The results will be monitor and compared to threshold value, which may lead to an Alarm. The result date will be stored to RAM in real time, which can be transmitted to a PC. The PC can show all the parameter values in real time.
