Answer / chethan

To improve the range of communication by preventing the
signal getting distorted. and for providing security.

Answer / lakkup

it is done so that the original information is converted to
a code ,so during transmission there is no possibility of
retrieving the original information i.e.,security based and
at the receiver side the code is converted to original
information

Answer / asrar

For digital transmission we need to code the signal.further
to provide high fidelity for long transmission and reduce
the distortion to minimum levels

Answer / sudeep

it is to reduce the channel errors in the transmission, it
will reduce the BER,

Answer / karan bhardwaj

It Is Done So Becuse Due To Codding We Secure The Data And
Only The perticular Receiver Who Know The Code Of Sender
Can Receive The Code By Decoding The Message. This is
Mainly Used In The Army Purposes Where We Need Very Much
Security.

Answer / anamika pandey

We are moving towards coding so as to:-
1)Use same same frequency and time repetedly by changing
coding technique.
2)For security purpose.
3)To minimize distortion of signal,crosstalk etc.
4)To increase capacity.
