In Ethernet when Manchester encoding is used, the bit rate is:

Answer: The bit rate is half the baud rate.

Explanation: In Manchester encoding each data bit is encoded by a transition in the middle of the bit period. This means each bit is represented by two signal-level intervals, so the symbol (baud) rate is twice the bit rate.

• Because there are two signal intervals per bit, baud rate = 2 × bit rate.

• Rearranging gives bit rate = baud rate / 2, i.e., the bit rate is half the baud rate.

• Example: 10 Mbit/s Ethernet uses Manchester encoding, which implies a 20 Mbaud signal.
