Abstract

DISPOSICION DE CONEXION DE SINTONIZACION PARA RECEPTORES DE RADIO O TELEVISION. CONSISTE EN LA DETERMINACION DE LA POSICION DE SINTONIZACION POR EL ESTADO DE UN CONTADOR, AL QUE, PARA LA VARIACION DE LA POSICION DE SINTONIZACION, SON APORTABLES IMPULSOS CONTADORES DESDE UNA FUENTE DE IMPULSOS CON UNA CONEXION QUE PRESENTA UN MIEMBRO DE TIEMPO, PARA AL FORMACION DE UNA SEÑAL DE SINTONIZACION. DESDE LOS IMPULSOS DEL CONTADOR SE DERIVA UNA SEÑAL DE MANIOBRA QUE REDUCE LA FRECUENCIA DE LOS IMPULSOS DE CONTADOR Y CON LA SEÑAL DE MANIOBRA EL MIEMBRO DE TIEMPO, QUE LIMITA LA VELOCIDAD DE VARIACION DE LA CONEXION DE SINTONIZACION, ELEVA SUS VALORES EN FUNCION DE LA FRECUENCIA CRECIENTE.
