Abstract
SISTEMA DE PROCESADO DE COMPONENTE DE LUMINANCIA EN RECEPTOR DE TELEVISION. UNA FUENTE (10) DE SEÑALES COMPUESTAS DE VIDEO ALIMENTA UN FILTRO DE PEINE (15), EL CUAL PROPORCIONA DOS SEÑALES. LA PRIMERA DE ELLAS (Y), FILTRADA (22), SE ACOPLA A UN COMBINADOR (30). LA SEGUNDA SEÑAL, FILTRADA (35), SE APLICA AL MISMO COMBINADOR, QUE PRODUCE UNA SEÑAL DE LUMINANCIA RESTAURADA. ESTA SEÑAL, INVERTIDA (32), ALIMENTA UNA RED DE CONTROL DE PICO HORIZONTAL (40), Y A UN SEGUNDO COMBINADOR (42). A ESTE TAMBIEN SE APLICA LA SEGUNDA SEÑAL FILTRADA (35), YA PROCESADA (50). LA SALIDA DE ESTE COMBINADOR (42) ALIMENTA UN PROCESADOR DE SEÑAL DE LUMINANCIA (58), QUE LA ENVIA A UNA MATRIZ (68). ESTE MATRIZ, COMBINANDOLAS CON LAS PROCEDENTES DEL PROCESADOR DE CROMINANCIA (64), PROPORCIONA LAS SEÑALES DE ENTRADA A LOS ELECTRODOS DE CONTROL DE INTENSIDAD DE IMAGEN DE UN CINESCOPIO (70).
