Unipolar Return to Zero (RZ) Coding Quiz

NRZ coding suffers from lack of synchronization, non-zero dc component and baseline wandering. RZ code overcomes these shortcomings by representing logic 1 with a non-zero voltage level and logic 0 with a zero voltage level, requiring transitions at the middle point of the bit interval.

The main features of Unipolar NRZ coding are ease of generation, requirement of only a single power supply, relatively low bandwidth, and a transmission normalized power for a single bit per unit line resistance that is double compared to their polar counterparts.

In RZ line coding, logic 1 is represented by a non-zero voltage level during a portion of the bit interval and a transition to zero at the middle point of the bit interval. Logic 0 is indicated by a zero voltage level during the entire bit interval.
