If the highest modulating frequency of the wave is (5 \mathrm{~kHz}), the number of stations that can be accomodated in a (150 \mathrm{~kHz}) bandwidth ?
Options
- A15
- B10
- C5
- DNone of these
Correct answer
A. 15
Step-by-step solution
Number of stations (=\frac{\text{ Band width }}{\text{ Band width/stations }});
Bandwidth per station (=2 \times 5 \mathrm{ kHz})
Total bandwidth (=150 \mathrm{ kHz}).
Number of stations (=\frac{150}{10}=15)
