Abstract:
A method for acquiring neurological signal data, comprising:producing a plurality of analog electrical data signals corresponding to a respective plurality of neurological data signals; combining said plurality of electrical data signals into a single combined analog data signal; modulating a radio-frequency signal by said combined data signal and transmitting said modulated radio-frequency signal; receiving and demodulating said radio-frequency signal so as to reproduce said combined data signal; demultiplexing said reproduced combined data signal and reproducing said plurality of electrical data signals representative of respective neurological signals; formatting said combined analog data signal to produce sets of data acquired within a common time frame and adding a header at the beginning of each said set prior to modulation of said radio-frequency signal so as to add a header at the beginning of said combined data signal and so that every header following the first header is inverted from its predecessor, said header comprising signal calibration information.
