Question

The number of amplitude modulated broadcast stations that can be accomodated in 300 khz band width for highest modulating frequency 15 khz will be

Answer 1

∵ Band width = 2 × n × highest modulation frequency
Here n is the number of amplitude modulated broadcast stations

Band width = 300 kHz
Highest modulation frequency = 15 kHz
so, 300 kHz = 2 × n × 15 kHz
⇒300 = 30n
⇒n = 10


Hence, number of stations = 10
