REQUIREMENTS FOR THE COINCIDENCE-PULSE SCANNING SYSTEM
Abstract
The circuitry requirements for raster scanning by the time coincidence of 4 pulses, where one pulse is introduced into each end of a horizontal delay line and a vertical delay line, are described. The time relationships among the pulses and the requirements of their accuracy were analyzed. From this analysis, criteria of linearity for the time-base voltage were derived that can be used to evaluate the feasibility of the various types of analog circuitry. This investigation also delineates the basic areas of the scanning system in which appropriate modifications need to be made. (Author)
