If the highest modulating frequency of the wave is 5 kHz , then the number of stations that can be accommodated in a 150 kHz bandwidth is
Options
- A20
- B15
- C10
- D5
Correct answer
D. 5
Step-by-step solution
Given, Highest modulating frequency, f_m=5 kHz =5 10^3 ~Hz Bandwidth ( BW ), f^ =2 f_m =2 5 10^3 ~Hz =10^4 ~Hz Total bandwidth, f=150 kHz =150 10^3 ~Hz Number of stations = f f^ = 150 10^3 10^4 =15
