For a television network, \(5 \times 10^5\) channels are granted. If the central frequency of the microwave link is \(25 \mathrm{GHz}\) and the alloted bandwidth for each channel is \(2 \mathrm{kHz}\), then how much percentage of the link is used for the network?
- A \(4 \%\)
- B \(10 \%\)
- C \(25 \%\)
- D \(5 \%\)
Answer & Solution
Correct Answer
(A) \(4 \%\)
Step-by-step Solution
Detailed explanation
Let \(x \%\) of link is used for network. Given, central frequency \(=25 \mathrm{GHz}\) \(=25 \times 10^9 \mathrm{~Hz}\) Bandwidth of channels \(=x \%\) of \(25 \mathrm{GHz}\) \(=\frac{x}{100} \times 25 \times 10^9=25 x \times 10^7\) Number of channel…
