The carrier signal is passed through the patient's body and modulated in accordance with the respirations of the patient to produce a modulated carrier signal. A carrier detection circuit is connected to receive the modulated carrier signal and produce a demodulated respiration signal. An ECG circuit also receives the carrier signal and filters out ECG signals. The respiration and ECG signals are passed to an analysis unit. Both the patient unit and analysis unit contain baseline correction circuits for maintaining a predetermined baseline. | |
