Description

med en kilde (Q2) for modulationssignaler og med afbøjningsviklingen (L.,) og tilfører en modulationsstrøm Π til tilbageløbsresonanskredsløbet (25) for herved at modulere amplituden af skanderingsstrømmen uden at modulere amplituden af forsyningsinduktansens impulsspænding. Modulationen kan forekomme ved en lodret takt for at tilvejebringe øst-vest pudeforvrængningskorrektion .with a source (Q2) for modulation signals and with the deflection winding (L. The modulation may occur at a vertical rate to provide east-west cushion distortion correction.
