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? Problem 1 Power 0.5 0.4 (mw) 0.3 0.2 0.1 %2 4 6 8 10 12 14 16 18 20 22 Frequency (Khz) [5 points] (a) What is the theoretical maximum signaling rate for a channel with the above frequency distribution? [6 points] (b) What is the theoretical maximum bit rate for this channel if a phase- amplitude modulated signal with 64 levels is transmitted over the channel? [6 points] (c) What is the actual maximum bit rate if the signal to noise (S/N) ratio for this channel is 33.111 dB? [5 points] (d) A modem has a baud rate of 2400 symbols/sec.
