- Derive the QPSK of overall scheme. probability of symbol errorMost 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. Explain why this code has a synchronization problem? b) Repeat part ) for Manchester encoding scheme and explain how the synchronization problem has been addressed.Determine the binary values for which the following SOP expression is equal to 1: XYZ + XYZ + XYZ + XYZ + XYZ Is this a standard SOP expression?
