Fecha de publicación: 27/06/2001 Fuente: Wipo "digitalization" An analog-to-digital converter 16 includes first and second analog-to-digital converters 22 and 24 both of which receive an input signal. The first analog-to-digital converter 22 is configured to be centered around a first signal level point while the second analog-to-digital converter 24 is configured to be centered around a second signal level point. A decoder 26 receives inputs from the two analog-to-digital converters 22 and 24 and selects between the first analog-to-digital converter 22 output and the second analog-to-digital converter 24 output.
