SEMICONDUCTOR MULTICHANNEL DIGITAL-TO-ANALOG CONVERTER WITH A VOLTAGE MEMORY,

A semiconductor multichannel digital-to-analog converter is described which was used jointly with a digital computer and which represents a reflection device. The required coordinates are recorded in the storage unit of the digital computer. Then, the storage cyclically delivers a parallel code which is fed to registers. From the latter, the signals go to summation matrices which produce analog voltages. These voltages -- via amplifiers -- are applied to voltage-storage units, from where the signals are fed to deflection devices. Circuits and individual assemblies of the converter are described.
