-NRZ encoding can lead to data corruption -NRZ encoding can also create unnecessary bandwidth usage -NRZ encoding can also create issues with synchronization

Sure, here's a brief explanation of potential issues with Non-Return to Zero (NRZ) encoding when a stream of continuous 0s or 1s is sent: 1. DC (Direct Current) Bias: - NRZ encoding sends a continuous stream of identical bits which can result in a direct current in the transmission medium. The longer the sequence of identical bits, the bigger this problem becomes, which can potentially influence the transmission capacity (Tomasi, 1999). 2. Lack of synchronization: - If there are no changes on the line, it becomes difficult for the receiver to synchronize its clock with the transmitter. Synchronization is essential to determine when one bit ends, and the next one begins. Without these transitions, synchronization loss can occur (Peyravi, 2005). 3. Baseline Wander: - If a long sequence of the same bits is sent over the line, it can cause a phenomenon called baseline wander. This results from the inability of the receiver to decide on the mid-point between the high and low voltage levels to distinguish between the ones and zeros (Gibson, 2002).
