Study of a Parametron on an Analog Computer

It is possible to describe the behavior of a parametron [1] by Mathieu's equation after introducing certain simplifications. However, for an accurate, quantitative analysis, one has to take into account the nonlinear periodic change of parameters. In order to study the behavior more accurately, especially the transient behavior, an analog computer was employed to simulate a low-speed parametron. The basic circuit of a variable-inductance parametron is shown in Fig. 1.
