Abstract
Perfeccionamientos en sistemas amplificadores de control automático de ganancia de la señal de crominancia en receptores de televisión en color para utilizar señales de crominancia compuestos que tienen componentes de impulsión y representativa de la imagen, del tipo que comprenden un primer amplificador que tiene por lo menos un terminal de entrada destinado a acoplarse a una fuente de señales de crominancia compuestas para proporcionar componentes amplificados representativos de la imagen en un primer terminal de salida; un segundo amplificador que tiene por lo menos un terminal de control destinado a recibir una primera señal de control de ganancia y que tiene por lo menos un primer terminal de salida en el cual se proporcionan componentes de ganancia controlada de la señal de crominancia representativo de la imagen.
