The characteristics of the linear computing elements of the general-purpose electronic differential an alyzer are discussed. Equivalent circuits are given for these elements. Criteria for optimization of the linear computing system in order to obtain maximum computational accuracy are given. Examples of the effects of optimization in improving system stability, transient response, and in increasing bandwidth of high- and medium-accuracy computation are shown.
