Question 1: Describe different types of NRZ encoding scheme?
Answer:
In NRZ encoding the level of signal is either positive or negative. NRZ is classified into 2 types:NRZ-L:
Level of the signal depends on the type of bit it represents.
Positive voltage usually means the bit is a 1 and a negative voltage usually means the bit is a 0.
NRZ-I:
The inversion of the level represents a 1 bit. A bit 0 is represented by no change.
NRZ-I is superior to NRZ-L (PAGE 73)
