摘要：An implantable medical device performs impedance measurement and

demodulation, such as for obtaining lead impedance measurements, or thoracicimpedance measurements, such as for extracting respiration, cardiac stroke, or fluidstatus information. A 4-point FIR filter demodulator can be used to demodulate a two-phase current excitation waveform. The demodulator can also be used to measure noisefor triggering a noise response. Among other things, an increased excitation current levelcan be used when noise is deemed to be present.
