Abstract

TRANSCODIFICADOR DE SEÑALES DE VIDEO MUESTREADAS A DIVERSAS FRECUENCIAS. EL TRANSCODIFICADOR TRANSFORMA EL CODIGO DE SEÑALES MUESTREADAS A UNA PRIMERA FRECUENCIA PARA OBTENER SEGUNDAS SEÑALES SINCRONIZADAS A UNA SEGUNDA FRECUENCIA. UTILIZA ELEMENTOS DE RETARDO PARA FORMAR MUESTRAS SUCESIVAMENTE RETARDADAS DE LA SEÑAL DE ENTRADA. DISPOSITIVOS SUBSTRACTORES FORMAN SEÑALES REPRESENTATIVAS DE LA DIFERENCIA DE AMPLITUD ENTRE MUESTRAS RETARDADAS SUCESIVAS. UNOS MULTIPLICADORES APLICAN UN MULTIPLICADO A LAS SEÑALES DE DIFERENCIA PARA FORMAR SEÑALES PONDERADAS, QUE FINALMENTE ENTRAN EN UN SUMADOR PARA FORMAR NUEVOS VALORES DE MUESTRA.
