Multisine and Binary Multifrequency Waveforms in Impedance Spectrum Measurement - A Comparative Study

  • Conference paper

Part of the IFMBE Proceedings book series (IFMBE,volume 37)

Abstract

The multisine and binary waveforms are usable as multifrequency excitation signals in measurement of impedance spectrum of biological objects. A comparative study of these waveforms is given for the case of multifrequency signals covering 3 frequency decades with 11 spectral components with octave based frequency distribution. It is shown in the paper that the multisine excitation signal can be optimized by adjustment of phases of the desired spectral components. Moreover, it is concluded that the binary multifrequency signal formed from the corresponding multisine waveform as the signum function of it, is much more effective than the optimized multisine signal.
