A Feature Extraction Method Using Linear Model Identification of Voltammetric Electronic Tongue

  title={A Feature Extraction Method Using Linear Model Identification of Voltammetric Electronic Tongue},
  author={Sanjeev Kumar and Arunangshu Ghosh},
  journal={IEEE Transactions on Instrumentation and Measurement},
A novel technique of feature extraction for a voltammetric electronic tongue is presented using system identification method with the subsequent synthesis of an equivalent circuit for black tea and then to predict the total theaflavin (TF) content in it. The equivalent circuit parameters for different tea samples are estimated using the current response data obtained from the voltammetric electronic tongue, on which system identification procedure is applied. These identified circuit parameters…
