If the highest modulating frequency of the wave is \(5 \mathrm{kHz}\), then the number of stations that can be accommodated in a \(150 \mathrm{kHz}\) bandwidth is
- A 20
- B 15
- C 10
- D 5
Answer & Solution
Correct Answer
(D) 5
Step-by-step Solution
Detailed explanation
Given, Highest modulating frequency, \(f_m=5 \mathrm{kHz}\) \(=5 \times 10^3 \mathrm{~Hz}\) \(\therefore\) Bandwidth \((\mathrm{BW}), f^{\prime}=2 f_m\) \(=2 \times 5 \times 10^3 \mathrm{~Hz}=10^4 \mathrm{~Hz}\) Total bandwidth, \(f=150 \mathrm{kHz}\)…
