METHOD AND A DEVICE FOR ADAPTING EEG MEASUREMENT SIGNALS
First Claim
1. A method for adapting an electroencephalography (EEG) measurement signal to the characteristic range of an electrocardiography (ECG) measurement signal, characterized in that said method comprises the steps ofproviding a conversion apparatus comprising an input interface for at least functionally connecting with a plurality of electrodes, a signal amplification means, and an output interface,receiving the EEG measurement signal in the conversion apparatus via said input interface,processing the received EEG measurement signal by at least said signal amplification means so as to represent the signal, in relation to at least one predetermined parameter, using a parameter value range characteristic to an ECG measurement signal, andtransmitting said processed EEG signal through the output interface in order to enable a receiving device to treat said processed EEG signal like an ECG measurement signal.
