摘要： A system and method for filtering a signal comprising: receiving a signal of interest; receiving a signal indicating that a stimulus has been applied; receiving the synchronized stimulus signal and signal of interest; recursively selecting a portion of the signal of interest associated with a stimulus being applied and assign the selected portion of the signal of interest to one of the plurality of buffers; combining all responses in each of said plurality of buffers; transforming the combination of all responses in each buffer to a transform space; comparing the transform components of the buffers to determine a scaling factor; applying the scaling factor to the spectral components of the buffers; performing an inverse transform on the result of combining the buffers to return to the time domain to produce a filtered signal, and outputting the filtered signal received from the processor.

摘要： An apparatus, method and system for collection of physiological electrical potential signals. In one embodiment, an apparatus for use in measuring electrical potentials in a subject (e.g. an animal or a human), having an amplifier being removably mountable to a ground electrode and electrically coupled to at least two signal electrodes, wherein the amplifier is configured to communicate with a signal processing device and indicate if one of the at least two signal electrodes is poorly affixed to, or detached from, said subject. In another embodiment, the at least two signal electrodes comprise a first signal electrode and a second signal electrode, and the amplifier is configured to detect differential electrical potential signals presented by the first signal electrode and the second signal electrode, amplify the differential electrical potential signals by a predetermined gain level to generate an amplified signal, and transmit the amplified signal to the signal processing device.
