Method and device for fast measurement of frequency response with scalable short chirp signals
摘要
<p>The present invention relates to a method and device for fast bioimpedance measurement of a biological object having dynamically varying in time parameters, wherein a chirp current signal is introduced into the object and a voltage response signal is measured and analysed by a processing unit for estimating the bioimpedance of the object. The chirp signal has a start frequency substantially in one end of the frequency range of interest and a stop frequency substantially in the other end of the frequency range of interest and a duration that is shorter or equal to the maximum measurement time. The running frequency of the chirp signal is changed from the start frequency to the stop frequency according to a predetermined formula.</p>
