ABSTRACT
Thus, a simple recursion formula can be implemented for an arbitrary number of active gases. From the wide variety of scenarios of samples and modeled responses, we have chosen the identification of CO and its concentration when it is sampled in combination either with CH4 or with EtOH. The modeled nose consists of four Taguchi sensors. The sample space contains CO with significant mixture of either CH4 or EtOH. Total concentrations vary between 500 and 2500 ppm, and with a, covering all ranges between 0 and 1 in steps of 0.1. A linear function for g(a) was chosen for the sake of simplicity but of course more complex options can be chosen.
