Q31.

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

Q32.

Purpose of a start bit in \text{RS-232} serial communication protocol is:
GateOverflow

Q33.

A serial transmission T1 uses 8 information bits, 2 start bits, 1 stop bit and 1 parity bit for each character. A synchronous transmission T2 uses 3 eight-bit sync characters followed by 30 eight-bit information characters. If the bit rate is 1200 bits/second in both cases, what are the transfer rates of T1 and T2?
GateOverflow

Q34.

In serial communication employing 8 data bits, a parity bit and 2 stop bits, the minimum band rate required to sustain a transfer rate of 300 characters per second is
GateOverflow
