Show answer & explanation
Correct answer: B
In Manchester encoding, each bit period is divided into two halves to ensure synchronization. A transition occurs in the middle of every bit, meaning the duration of a single signal level (pulse width) is half the bit period. In contrast, straight binary encoding maintains a constant level for the entire bit period. Therefore, the pulse width in Manchester encoding is half that of straight binary encoding.
