The Noise Immunity of Parametron-Type Logic Circuits,

The relations between a Logic-circuit structure and its coupling coefficient are considered. For a parametron logic circuit with a 3-cycle excitation, the permissible number of output coupling is given in a figure. By a judicial selection of coupling circuits and phase relations, the number of outputs of the parametron can be increased despite considerable back-information signal. In the case of several N inputs and majority control, the spread of control signals becomes important. The relation between N and the relative error is given. Author
