Transmission of analog signals with the use of optoelectronic separators

摘要

The paper includes discussion on the basic structures of analog signal separators with optoelectronic optocouplers with particular focus on the features significant to provide the linearity of transformation characteristic. It also includes the evaluation of transformation characteristic linearity of a selected optoelectronic current signals separator. For static transformation characteristics, determined experimentally, I_O = f(I_I) the nonlinearity and approximation errors were compared. Upon comparison of the value of such errors, conclusions were formulated on determining the optimum use of the separator's transmission abilities.
