A bandwidth of 10 M H z is available for A M transmission. If the maximum audio signal frequency used for modulating the carrier is not to exceed 5 kHz, how many stations can be broadcasted within this band simultaneously without interfering with each other?

Correct answer

1000

Step-by-step solution

Bandwidth required for each station = 2 × maximum frequency of audio signal 2 × 5 = 10 k H z Number of stations which can be broadcast within bandwidth of 10 M H z = 10 × 10 6 10 × 10 3 = 1000
