LEAD-IN: What is Digital Signal Processing?
The signals relevant for digital signal processing are not of digital nature at all. Before the digital part of a
system starts operation, the incoming
signals have to be fed into an analog-to-
digital-converter. Subsequently, highly
complex algorithms can be applied to the
digitized signals. With an analog system
their realization would not be possible.
Examples for such algorithms are speech
coding, noise suppression, acoustic echo
compensation, speech recognition,
speaker localization and identification as
well as compression of speech and video
data (MP3 resp. MPEG).
