Analog-Digital Device for Modeling Problems of Nonstationary Thermal Conductivity

摘要

The device contains a network of ohmic resistances and a device for setting the boundary conditions. To increase the accuracy of simulation, the device contains a code-to-analog converter for each node, which operates alternately in a storage and a voltage setting mode. There is also one analog-to-code converter common to all the nodes, which is connected sequentially through an electronic switch to the nodes of the network. Codes proportional to the voltages at these points are supplied to the inputs of the code-to-analog converters operating in the storage mode.
