[amp_mcq option1=”Less than 5″ option2=”Less than 10″ option3=”More than 10″ option4=”None of the above” correct=”option3″]<\/p>\n
The correct answer is: C. More than 10.<\/p>\n
The Q factor of a tuned amplifier is a measure of its selectivity. A higher Q factor means that the amplifier is more selective, and will only pass a narrow band of frequencies. This is important for applications where it is necessary to reject noise or interference from other frequencies.<\/p>\n
The Q factor of a tuned amplifier is typically in the range of 10 to 100. A Q factor of 10 means that the amplifier will pass a band of frequencies that is 10 times wider than the center frequency. A Q factor of 100 means that the amplifier will pass a band of frequencies that is 100 times wider than the center frequency.<\/p>\n
A higher Q factor also means that the amplifier will have a higher gain. This is because the amplifier will be able to amplify the desired signal without amplifying the noise as much.<\/p>\n
However, a higher Q factor also means that the amplifier will be more susceptible to oscillation. This is because the amplifier will be more sensitive to small changes in the input signal.<\/p>\n
Therefore, the choice of Q factor for a tuned amplifier depends on the specific application. For applications where it is necessary to have a high degree of selectivity, a higher Q factor is desirable. However, for applications where it is necessary to avoid oscillation, a lower Q factor is desirable.<\/p>\n
