The AFSK system described in the text operates at 1200 bits per second using an FM signal modulated by tones at 1200 and 2200 Hz, with a frequency deviation of 5 kHz. Calculate the efficiency of this system in bits per second per hertz of bandwidth by using Carson's rule (see Chapter 4) to calculate the approximate radio frequency bandwidth for this system. Is this system bandwidth-efficient
