These sensors show different problems, e.g., nonlinearities and slow time-response, which can be partially solved by digital signal processing. Our approach is based on building a nonlinear inverse dynamic system. Results for different identification techniques, including artificial neural networks and Wiener series, are compared in terms of measurement accuracy.8 p.application/pdfeng(c) IEEE, 1998Detectors de gasosSèries (Matemàtica)Gas detectorsSeries (mathematics)info:eu-repo/semantics/article143633info:eu-repo/semantics/openAccess
