Question

what is the role of scrambling in signal encoding technique​

Answer 1

Answer:

Scrambling is a technique that does not increase the number of bits and does provide synchronization. Problem with technique like Bipolar AMI(Alternate Mark Inversion) is that continuous sequence of zero's create synchronization problems one solution to this is Scrambling.

Answer 2

Scrambling is a digital encoding technique that is used in modern data communication schemes and can principally provide aid in retrieving information from received data enhancing synchronization between the transmitter and the receiver.
