Onoon the Theory of Functional Generators Operating on a Cathode Ray Tube

摘要

This report describes a functional transformerphotoformer, serving for the transformation of graphic images of an analytical or experimental function of a certain variable into an electric form of voltage for subsequent utilization during measurements and adjusting various electron blocks or introduction into a modeling device. The device, in essence, is a follow up system by position, of which the operating element is the beam of a cathode ray tube (CRT), enveloping the profile of a mask corresponding to a nonlinear dependence fixed for reproduction. The calculations for a photoformer, with band pass of several kc and accuracy of 1-2 per cent, are presented. The mode of operation of the arrangement and the basic static equations of the system are formulated. It was shown that in certain limits, the system is approximately linear.
