Abstract :
This paper presents a method that takes into account the switching uncertainties in the signal path of the measurement devices during the identification of device models. Switching phenomena in the measurement instrument, like switching attenuators, induce jumps in the measured input-output characteristic that can be much larger than the noise contributions. The proposed method eliminates the subsequent model error by considering these jumps as a signal path state dependent stochastic contribution
