Advantages Of Digital Signal Processing Over Analog Signal
Processing
Digital signal processing has following advantages:
1. Digital signal processing operations can be changed by
changing the program in digital programmable system, i.e.,
these is flexible systems.
2. Better control of accuracy in digital systems compared
to analog systems.
3. Digital signals are easily stored on magnetic media such
as magnetic tape without loss of quality of reproduction of
signal.
4. Digital signals can be processed off line, i.e., these
are easily transported.
5. Sophisticated signal processing algorithms can be
implemented by DSP method.
6. Digital circuits are less sensitive to tolerances of
component values.
7. Digital systems are independent of temperature, ageing
and other external parameters.
8. Digital circuits can be reproduced easily in large
quantities at comparatively lower cost.
9. Cost of processing per signal in DSP is reduced by time-
sharing of given processor among a number of signals.
10. Processor characteristics during processing, as in
adaptive filters can be easily adjusted in digital
implementation.
11. Digital system can be cascaded without any loading
problems.
