What is the disadvantages in using nrz encoding and how does rz encoding attempt to solve the problem
Answers
Answer:
The advantages and disadvantages of using NRZ and RZ are quite different. Basically, these are a technique which is used for the purpose of converting the analog signal to a digital signal. The main difference between them is their characteristics of changing there state.
Explanation:
In NRZ the pulse does not return to zero, it simply continues it's a path, whereas the RZ changes the impulse and brings to the ground level when there are variations.
Answer:
"NRZ code is a string of 0s and 1s .
It prohibits the synchronization of transmitter clock with receiver clock . The receiver gets continuous voltage and determines how many bits are sent relying on its clock which may or may not be synced with the sender clock.
In RZ encoding , the solution is to include synchronization in the encoded signal.
