Correct Answer :   50 μF

Correct Answer :   To allow low frequencies to pass through while attenuating high frequencies

Explanation : A low-pass filter is designed to allow low-frequency components of a signal to pass through while attenuating high-frequency components. It effectively “filters out” the higher frequencies beyond the cutoff frequency, allowing only the lower frequencies to be present in the output signal.

Correct Answer :   Band-pass filter

Explanation : A band-pass filter is employed to separate specific frequency bands from a complex signal. In speaker systems, band-pass filters are commonly used to separate audio frequency bands and direct them to the appropriate drivers, ensuring each driver receives the frequency range it is designed to reproduce.
