Abstract:
1. A baseband receiver, comprising: a receiver input port, configured to receive a baseband signal generated in response to electrical activity in tissue of a human patient; a modulator, configured to modulate a local oscillator signal with the baseband signal; an isolating device configured to receive the modulated local oscillator signal at an input port of the device and in response to generate a modulated output local oscillator signal at an output port of the device; an input reference rail; an output reference rail, the input reference rail and the output reference rail being different and electrically insulated from each other, the received baseband signal is referenced to the input reference rail; and a demodulator configured to demodulate the modulated output local oscillator signal with the local oscillator signal so as to recover the baseband signal, the recovered baseband signal is referenced to the output reference rail.
