Assuming that audible sound has a maximum frequency of 10000 Hz, what is the maximum number of radio channels that can fit onto the FM radio band without overlap? (The frequency range of FM is 88 MHz to 108 MHz).

Solutions

Expert Solution

frequency of massage signal , fm = 10000 Hz

band width of massage signal W = 2 fm =20000 Hz

FM band width , WFM = 108 - 88 = 20 MHz
