Most Digital transmission are "self-clocking " in that they derive the bit synchronization from the signal itself. To do this, the system use the transitions between positive and negative voltage levels. These transition help define the boundaries of the bit intervals. a) Plot the NRZ-L signal for the data stream 4 bits of 1s followed by 4 bits of Os.
