Factorial experiment planning on research of immunosensor membrane

Factorial experiment of research of immunosensor membrane dynamic behavior is being planned. Three input guided factors are supplied to the membrane and are changed acording to the certain program during the experiment. Output index is current, taken from the sensor and containing together with the useful signal an additive noise, that's why it represents random sequence. The aim of the experiment is the establishment of the opportunity of using of the spectral characteristics, generated by realizations expansion into the series of Adamar–Wolsh approximation functions, as well as the establishment of response dependence on the considered factors.
