A modem has a baud rate of 2400 symbols/sec. What would be the bit rate for this modem if its phase-amplitude constellation is as follows: [2 points] (e) A voice grade modem has a maximum data rate of 14,400 bps. What would be the maximum data rate of that modem if the number of points in its constellation were doubled?
