Claim Text:
1. A device for monitoring biopotentials of biological tissue through a plurality of electrodes, the device comprising: a configurable receiver circuit having a plurality of channels for receiving a plurality of biopotential signals from a biological tissue via a plurality of inputs coupled with the electrodes, each channel being configured to substantially remove a DC (direct current) offset from a corresponding one of the plurality of biopotential signals and then band-pass amplify the corresponding one of the biopotential signals at a configurable particular frequency range based on one or more frequency control signals; a controller circuit operable to receive commands for configuring or reconfiguring one or more frequency characteristics pertaining to receiving each biopotential signal; an impedance measurement module for generating a capacitively-coupled AC (alternating current) current waveform, having an amplitude and frequency, that is applied to a particular input coupled to a particular channel to measure a voltage signal received at the particular channel in response to the AC current waveform applied to the particular input, wherein the controller is further configurable to program the impedance measurement module to generate the capacitively-coupled AC current waveform to be applied to the particular selected input so as to monitor the impedance of the corresponding one of the electrodes by calculating the impedance based on the measured voltage signal received at the particular channel, wherein the controller is further configurable to automatically generate the one or more frequency control signals based on the commands and output the one or more frequency control signals to the configurable receiver circuit, wherein the controller is further configurable to output a representation of each biopotential signal and a representation of the calculated impedance to an analyzer device that is configured to analyze the representation of each biopotential signal and the representation of the calculated impedance.
