Abstract

Inventia se refera la un generator TV si dinte de fierastrau pentru baleiaj vertical, utilizabil împreuna cu un ansamblu de deflexie pentru tub cinescop într-un receptor de televiziune, sub forma de circuit integrat ce cuprinde doua condensatoare conectate în serie si o sursa de curent constant a condensatoarelor si o sursa de tensiune pentru a forma o tensiune în dinte de fierastrau pe condensatoare, de asemenea intervalul de crestere a dintelui de fierastrau este determinat de componente exterioare cu un divizor de tensiune format în circuitul integrat pentru corectarea linearitatii reactiei.
