[amp_mcq option1=”Increased” option2=”Constant” option3=”Decreased” option4=”None of the above” correct=”option3″]
The correct answer is C. Decreased.
The power-bandwidth trade-off is a fundamental limitation in wireless communication. In order to transmit a signal over a distance, a certain amount of power is required. The amount of power required is inversely proportional to the bandwidth of the signal. This means that if we want to reduce the transmit power requirement, we need to decrease the bandwidth of the signal.
There are a few ways to do this. One way is to use a modulation scheme with a lower bandwidth. Another way is to use a directional antenna, which focuses the signal in a particular direction and reduces the amount of power that is wasted in other directions.
Decreasing the bandwidth of a signal has a few consequences. First, it reduces the amount of information that can be transmitted in a given amount of time. Second, it can make the signal more susceptible to interference. However, in many cases, the benefits of reducing the transmit power requirement outweigh the disadvantages of decreasing the bandwidth.
Option A is incorrect because increasing the bandwidth would require more power. Option B is incorrect because the bandwidth is inversely proportional to the transmit power requirement. Option D is incorrect because the bandwidth needs to be decreased in order to reduce the transmit power requirement.
