<p>An apparatus or method can be configured to receive first information indicative of respiratory effort of a subject from a first piezoelectric film sensor and second information indicative of respiratory effort of the subject from a second piezoelectric film sensor, and to process the received first and second information to produce an electronic signal output indicative of respiratory effort of the subject, the processing including averaging the received first information using a first differential amplifier and signal integrator with resistive reset to reduce differential noise and to attenuate common-mode noise, and averaging the received second information using a second differential amplifier and signal integrator with resistive reset to reduce differential noise and to attenuate common-mode noise.</p> |
