Abstract
Un sistema perfeccionado de recepción de televisión en color que utiliza componentes de señal de alta frecuencia inferidas para reducir infidelidades de color en regiones de transición de color que comprende: medios de circuitos de corrección que responden a una señal de televisión de color compuesta recibida para producir, para cada una de una o más señales componentes de color de ancho de banda reducido, una componente de señal de color de alta frecuencia incremental inferida que es sustancialmente proporcional en valor instantáneo al producto de (1) una señal representativa del valor de la porción de alta frecuencia de la señal monocromática de banda ancha, (2) una señal representativa de la velocidad de variación con el tiempo de la respectiva señal componente de color de ancho de banda reducido y (3) la inversa de una señal representativa de la velocidad de variación con el tiempo de la porción de baja frecuencia de la señal monocromática de banda ancha.
