Abstract

Se divulga un transmisor para transmitir una señal de informacion digital teniendo una primera frecuencia de muestreo (fsl) vía un medio de trasmision. La señal de informacion digital es filtrada pasabaja (10) y submuestreada (12) de manera a obtener un componente de frecuencia baja de la señal de informacion digital. La señal es transmitida vía el medio de trasmision (TRM). Además el componente de baja frecuencia es supermuestreada (22) y filtrada (28) y en seguida sustraída (34) a partir de la señal de informacion digital original. La señal modificada así obtenida es también trasmitida.
