DEFINITION

Classification: 315/387

(under subclass 364) Subject matter wherein the electrical circuitry connected to the deflection means includes at least one feedback loop.

(1) Note. Compensation for nonlinearity in the deflection of the cathode-ray caused by the deflection means or components of the deflection circuit are included here.
