Abstract

DISPOSITIVO GENERADOR DE TERCEROS ARMONICOS PARA TELEVISORES EN COLOR. ESTA FORMADO POR UNA FUENTE DE SEÑALES (10) QUE PROPORCIONE UNA ONDA SINUSOIDAL A AL FRECUENCIA DE LA SEÑAL SUBPORTADORA DE COLOR. LA SALIDA DE LA FUENTE ALIMENTA UN AMPLIFICADOR LIMITADOR (30) Y UN AMPLIFICADOR LINEAL (20), CONSTRUIDO A BASE DE TRANSISTORES Y RESISTENCIAS, QUE GENERAN UNA SEÑAL DE ONDA CUADRADA Y UNA SEÑAL SINUSOIDE RESPECTIVAMENTE. ESTAS DOS SEÑALES SE COMBIANAN EN UN CIRCUITO COMBINADOR (40) Y LA COMPOSICION DE AMBAS DA LUGAR A UNA RESULTANTE FORMADA POR TODOS LOS ARMONICOS IMPARES EXCEPTO EL DE PRIMER ORDEN.
