Abstract

La presente se relaciona con un patron de sincronizacion predeterminado (40), un así llamado campo VFO, en, por ejemplo, los cabezales 3 de un portador de informacion. El patron de sincronizacion propuesto (40) consiste de secuencias de marcas y espacios 3T (41), de marcas y espacios 8T (42) y de marcas y espacios 5T (43). Esta secuencia de patrones es ventajosa para establecer el rango dinámico de un amplificador de Ganancia Automática Controlada (AGC) ubicado dentro de un dispositivo que lee el portador de informacion.
