ABSTRACT:
A system and method of sensing relatively low magnitude signals of interest in a sensing environment with at least intervals of relatively high magnitude noise of comparable or overlapping frequency spectra as the signals of interest. The systems and methods can be implemented in an efficient, low-power manner to facilitate long term monitoring of low magnitude physiologic signals, for example in an in vivo or implantable manner. An amplifier can be arranged with a threshold detector driving a normally closed switch such that the input to or output from the amplifier can be opened when the noise exceeds a threshold. A filter, such as a moving average filter, can be included to smooth the amplified output and compensate for the amplified signal lost when the threshold is exceeded. The systems and method facilitate implantable nerve sensing in high noise environments, such as from myopotentials.
