[amp_mcq option1=”passes lower-frequency signals and reduces higher-frequency signals” option2=”passes higher-frequency signals and reduces lower-frequency signals” option3=”has no effect on ac signals” option4=”increases the level of all frequencies by a significant amount E. None of the above” correct=”option1″]
The correct answer is: A high-pass filter passes lower-frequency signals and reduces higher-frequency signals.
A high-pass filter is a filter that passes signals with frequencies higher than a certain cutoff frequency and attenuates signals with frequencies lower than the cutoff frequency.
Option B is incorrect because a high-pass filter reduces higher-frequency signals, not lower-frequency signals.
Option C is incorrect because a high-pass filter does have an effect on ac signals, it passes ac signals with frequencies higher than the cutoff frequency and attenuates ac signals with frequencies lower than the cutoff frequency.
Option D is incorrect because a high-pass filter does not increase the level of all frequencies by a significant amount, it only increases the level of frequencies higher than the cutoff frequency.
Option E is incorrect because a high-pass filter is a type of filter, not none of the above.
