Abstract
CIRCUITO PARA EFECTUAR LA FORMACION EN MATRICES DE LAS SALIDAS DE LA SEÑAL DE DIFERENCIA DE COLOR DE DEMODULADORES DE COLOR EN CONTRAFASE. PRESENTA UN PAR DE DEMODULADORES DE COLOR EN CONTRAFASE (10) Y (20), QUE TIENEN COMO MISION GENWERAR LAS SEÑALES DE DIFRENCIA DE COLOR (+-I Y+-Q) A PARTIR DE LA RECUPERACION DE LA SEÑAL DE DIFERENCIA DE COLOR DE LA SUBPORTADORA DE COLOR MODULADA. TRES CIRCUITOS AMPLIFICADORES DIFERENCIALES (70, 80, 90) ENTREGAN SUS SEÑALES A TRES REDES DE DESPLAZAMIENTO DE NIVEL (100, 110, 120).
