Question

Quizplus · Accepted Answer

In a return to zero (RZ) data format, a single pulse during a bit time represents a logical '1', and the absence of a pulse represents a logical '0'. This format is characterized by the signal returning to the zero level midway through each bit period, which helps in synchronization and distinguishing between bits.
