Abstract
DISPOSITIVO PARA LA LIMITACION DE UNA SEÑAL DE LUMINANCIA, DESTINADO ESPECIALMENTE PARA PROTEGER LOS PASOS DE POTENCIAL DE UN EMISOR DE TELEVISION, MONOCROMATICO O DE COLOR, CONTRA LAS SOBRECARGAS, EN CASO DE MODULACION POSITIVA, Y PARA EVITAR LA PERTURBACION EN LA TRANSMISION DEL SONIDO EN FRECUENCIA MODULADA, EN CASO DE MOLULACION NEGATIVA. CONSTA DE UN DESCRESTADOR FORMADO POR UN DIODO (5) Y UNA RESISTENCIA (R ), EL CUAL SUPRIME LA SEÑAL DE LUMINANCIA POR ENCIMA DE UN VALOR DE UMBRAL DETERMINADO; DE MEDIOS REGULADORES (2) DEL UMBRAL DE DECRESTADO; Y DE UN AMPLIFICADOR (14) CUYA GANANCIA AUMENTA CUANDO LA AMPLITUD DE LA SEÑAL ALCANZA EL UMBRAL DE DESCRESTADO, ESTANDO CONSTITUIDO POR UN AMPLIFICADOR OPERACIONAL (3) Y POR VARIAS RESISTENCIAS (R , R , R ), Y SITUADO AGUAS ARRIBA DEL DESCRESTADOR.
