Digital Signal Processing in
Life
DSP
• In communication systems, the received
waveform is usually categorized into the desired
part containing the information and the
extraneous or undesired part.
• The desired part is called signal: voltage as a function of time
or current as a function of time
• The undesired part is called noise
• Digital Signal Processing
• Signal carries some kind of information available for
observation
• Processing means to extract some useful information. It will
be a nondestructive ‘transformation’ of the given data signal
• Digital means that the processing is done with digital
computer / hardware
• Analog Devices is enhancing the driving
experience by bringing living room quality
audio and video to the automobile
– Fujitsu Ten adopts Analog Devices SHARC
DSP to implement acoustical space control in
automobile audio systems

• dspGuru's purpose is to promote resource-sharing among
DSP designers. As a center for DSP information exchange,
dspGuru has several goals:
– To provide "how to" information about DSP: tutorials for
beginners, tips and insights of interest to intermediate and
advanced DSPers.
– To provide online reference information.
– To provide a comprehensive, well-organized, and up-to-date set
of DSP links to help you quickly locate DSP resources on the
'net.
– To coordinate the development of "open source" software for
use in Digital Signal Processing. This is our OpenDSP (sm)
intiative.
