摘要： The present invention relates to a method (50) for detecting a plurality of useful signals in a total signal. Said useful signals correspond to radioelectrical signals emitted by different terminals in a multiplexing frequency band. Said method comprises steps for: - calculating (51) a plurality of spectrograms that have a compensated linear frequency drift and are respectively associated with different linear frequency drift values; and for each analysis frequency and each spectrogram, - performing time envelope filtering (52) of the values at the different times for analyzing said spectrogram at said analysis frequency by means of a filter representing a reference time envelope of the useful signals. A useful signal is detected at an analysis time and at an analysis frequency if a predefined detection criterion is verified by the value from a spectrogram resulting from filtering, that is, a so-called "filtered spectrogram," for said analysis time and said analysis frequency.

摘要： A sensor circuit usable with capacitive sensors in an electrical potential sensing network is provided. The sensor circuit provides bias current while maintaining a high input impedance for signals in a frequency band of interest by positive feedback of a filtered measurement through a finite impedance. The sensor circuits are suited for technologies such as, but not limited to electroencephalography (EEG), electromyography (EMG) and electrocardiograms (ECG). A neurofeedback system utilizing the capacitive conduction sensor is also described.

摘要： Values representative of modulation signal components are extracted from a modulated signal. The modulated signal contains a modulation signal. A local clock signal is developed which correlates in time to the modulated signal and has a plurality of non-overlapping phase sectors per cycle. The modulated signal is accumulated into an accumulated value, separately for at least one phase sector of one cycle of the local clock signal. Each accumulated value is representative of a modulation signal component. The modulated signal accumulated is of an amount representative of the mathematical integral of the modulated signal during each phase sector of the local clock over which the modulated signal is accumulated.
