*DIGITAL SIGNAL PROCESSING*
(aka ‘DSP’)
.
[‘signal processing’ is a ‘subfield’ of [‘mathematics’ / ‘information’ / ‘electrical engineering’] that concerns the [‘analysis’ / ‘synthesis’ / ‘modification’] of ‘signals’…
…which are broadly defined as “functions conveying ‘information’ about the ‘behavior’ (or ‘attributes’) of some phenomenon such as…)
.
*sound*
*images*
*biological measurements*
.
.
(for example, ‘signal processing techniques’ are used to improve…)
‘signal transmission fidelity’
‘storage efficiency’
‘subjective quality’
.
(‘signal processing techniques’ can ’emphasize’ (/ ‘detect’) components of interest in a ‘measured signal’)
