If the band width is 1.6 x 1012 Hz, how many communication channels can be obtained with 16 KHz band width radio signal?

  1. 108
  2. 1011
  3. 1010
  4. 1015

Answer

Bandwidth = 1.6 x 1012 Hz = 16 x 1011 Hz

Bandwidth of one signal = 16 x 103 Hz

Therefore,

Number of communication channels = (16 x 1011)/(16 x 103) = 108

The correct option is A.
