Fig. 11.2. Relation between baud and bit rates.

Fig. 11.2 (a) shows the baud rate equal to bit rate. Fig. 11.2 (b) and (c) shows the baud rate equal to one-half and one-fourth of bit rate respectively. It is proved that up to 2400 bauds may be transmitted reliably through a PSTN voice channel. By increasing the signal levels, the effective bit rate increases.

For low-speed applications, the difference between baud and bit rate are insignificant. Thus 300 and 1200 bps modems orginally used with personal computers were frequently referred to as 300 or 1200 baud modems.
