DEFINITION

Classification: 315/367

(under subclass 364) Subject matter wherein the electrical circuit includes means, having an input responsive to digital signals, to convert the digital signals into an analog signal, which analog signal is applied to the deflection means.

(1) Note. The bulk of the patents here have an electrical multiple output register responsive to digital signals wherein the multiple outputs are all connected to the deflection means whereby the sum of the outputs determine the extent of the deflection of the cathode-ray beam within the cathode-ray tube.

SEE OR SEARCH THIS CLASS, SUBCLASS:

8.51, for counting circuits responsive to digital pulses which cause a cathode-ray tube to store in analog fashion the sum of the pulses.

368.12+, for this subject matter in a color convergence control circuit
