Abstract

Se describe un método de adquisicion de datos que combina adquisicion sincronizada, amplificada y, si se requiere, ecualizada en un paso con sincronizacion de palabra. En el corazon del método esta un preámbulo que empieza con una repeticion de palabras idénticas P las cuales tienen una longitud que concuerda con la longitud de la palabra codigo. Preferiblemente basado en el inverso bitio por bitio de P. Las principales atracciones de la técnica son simplicidad, velocidad, y robustez.
