PERFECCIONAMIENTOS EN SISTEMAS DE CONTROL AUTOMATICO DE GA-NANCIA DE CROMA. |
摘要 |
<p>Cascaded first and second gain-controlled amplifiers are used in the chrominance channel of a color television receiver. The gain of the first amplifier is controlled by an ACC loop employing a noise-immune detector to detect color burst information. The gain of the second amplifier is controlled by the output of a peak detector which detects picture-interval information at the output of the second amplifier. An ACC system with improved performance during the reception of noisy signals results.</p> |
