3. Audio signal processing some time reffered
as audio processing,is the intentional
alternation of auditory signals, often
through an audio effect. As audio signal
may be represented in digital or analog
format, signal processing occure in either
domain. Analog processor operate on
electrical signal while digital signal operate
mathematically on the digital representation
of that signal.

4. Audio signal are sound waves.
_logitudinal waves which travels
through air, consisting of
compression & rarefactions .
These audio signal are measured in
bels or in decibels.
Audio processing are necessary for
early radio brodcasting,as there
were many problem with studio to
transmitter link.
