Modem
Consider a communications channel with a passband of 3 kHz to 27.4 kHz. A modem will be connected to this communications channel and the modem will operate with a signaling rate that is 0.56 the maximum allowable signaling rate for this communications channel. The modem uses a modulation technique with 512 different symbols (for example; 512 QAM). What is the data rate (in bits per second) of this modem?
