VERFAHREN UND SYSTEM ZUR DIGITALEN SIGNALVERARBEITUNG.

摘要

The signal processing system (S) allows the signal word width to be extended before combining the digital signals with a digital auxiliary signal (H) with a frequency above the highest frequency in a frequency band central on the sampling frequency. The amplitude of the auxiliary signal is dependent on one of the lowest value bits of the processed digital signals. Pref. the auxiliary signal comprises a minusoidal signal or a bandwidth limited noise signal combined with the digital signals via a digital addition stage (3).
