The number of amplitude-modulated broadcast stations that can be accommodated in a 300 kHz bandwidth for the highest modulating frequency 15 kHz will be:

Options

  1. A15
  2. B20
  3. C8
  4. D10

Correct answer

D. 10

Step-by-step solution

If modulating frequency is 15   kHz   then the bandwidth of one channel = 30   kHz . A number of channels accommodate. = 300   kHz 30   kHz = 10 .
